The 24-Hour Art Practice

Dr. Oei Hong Djien, Indonesia

Run Time : 58 minutes

Ongoing project : 2011 to date


The film traces the journey of Dr. Oei (OHD), a whimsical godfather of Indonesian art who amassed one of the most significant collections of modern Indonesian art by adopting a round-the-clock open-door policy for sellers and visitors to his home. When he was alleged with attempting to authenticate fake works in his collection, the Indonesian art world became incensed and knotted over issues of provenance, authentication and accountability.



The 24-Hour Art Practice offers unprecedented revelations and insights on one of best-known collections of modern Indonesian art and its founder Dr. Oei Hong Djien. This independent film unveils the eccentricities of Dr Oei’s collecting strategies, including opening his residence around the clock for art visitors; it also probes the recent launch of Oei’s private museum and the reactions of the art community.


This film takes us beyond the sensational polarisation of detractors and supporters of Oei’s museum, and raises greater issues of accountability, authenticity and provenance that are crucial for Indonesian art development and legacies.


This film traces the journey of Dr. Oei Hong Djien (OHD), a whimsical 75 year old art collector from Magelang in Central Java, Indonesia. Over 30 years, he amassed one of the most important collections of modern art in Indonesia by espousing a unique open house "art sourcing" policy: his residence filled with art that is worth millions of dollars has been open to walk-in artists, art scholars, enthusiasts and visitors round-the-clock. This is not without issues. The solution came in the form of a new off-residence museum for public access. At its inauguration, a scandal  alleging fake works in his collection surfaced on Facebook and resulted in a detailed “exposé”  in the nation's highest circulated publication,  Tempo magazine.  In the name of protecting national heritage for posterity, OHD is challenged to respond to pressing calls to declare provenance and prove the authenticity of specific works by artists of national significance in his private museum.


Set in the emerging art scene of Indonesia, this is the story of a singular collector and his unique ways of collecting, curating and sharing art works in his collection. It is also a story about the challenges faced by private art collecting in Indonesia and the expectations of the larger community when a collection is perceived to be representing the nation. The film addresses and raises for thought, issues of authenticity and provenance, of responsibility and accountability, of the tensions between public legacies and private succession plans for a cultural collection, and points to the crises of a proliferation of opinions but dearth of authenticating methodologies and authoritative sources.

Uli Sigg, Switzerland

Run Time : 30 minutes

Ongoing project: 2011 to date




The journey of Swiss art collector, Uli Sigg, into the heart of the Chinese cultural space, as a preserver and custodian of cultural assets which is not his own -- challenging ethical thresholds and navigating cross-cultural boundaries. Through the lens of art, it reveals that dogged determination coupled with passion can sometimes supersede cultural affinity and geographical proximity in instituting legacies. 



Uli Sigg is a Swiss national whose fascination with China saw the establishment of the largest and most significant collections of Chinese contemporary art in the world.


Sigg chanced upon post-1978 China when he was sent to Beijing as a businessman and later, as Swiss Ambassador when its economy underwent sweeping changes. There, he looked to contemporary art for access to information on Chinese society and learnt that works by Chinese artists were not collected, either by private individuals or public institutions. Thus began his 20-year quest to document these productions with the express intention of donating them back to China one day. But as a Westerner, the odds were stacked against him: he did not speak the language, nor did he begin with any understanding of Chinese culture or artists.

As a media professional, Sigg is no stranger to headlines and controversies. But it is the unconventional art that he collects that has put him on the hot seat as he bears the brunt of suspicion and criticisms. In trying to mirror Chinese art productions, Sigg makes the subjective objective, putting aside personal tastes to ensure completeness of his “historical document”. Ironically, with the meteoric rise of the Chinese art market, Sigg finds himself priced out.


1,000 door-to-door studio visits and 2,200 works later, his vision was realised under a part gift/part purchase to M+ museum in Hong Kong valued at $163 million, comprising 70% of his collection. The partial donation to Hong Kong, originally conceived to deliberately avoid the fate of censorship within mainland China, met with a changed political order in Hong Kong years later.  

This is an excerpt of a long form documentary in production.  This film was awarded the short film grant from the Media Development Authority of Singapore.

The films continue to be invited for screenings and discussions in many art and educational institutions around the world.

"The Authentication in Art Congress found Patricia's film necessary to be shown at the Authentication in Art Congress in May 2016. There were some 160 experts who were present, some with the practice of collecting [art] this way. Personally, I found the documentary not only enlightening from a professional point of view, but very strong because Patricia 'grows' with the turn that also overtook her during the duration of the project. This open-mindedness makes it a strong masterpiece that transcends cultures and time periods."

Organiser, Authentication in Art Congress



"The 24-Hour Art Practice" by Patricia Chen.  For some time I have sought for a contact with IDFA, to re-introduce this documentary, after I saw it at the "Authentication in Art" conference, this year in May. The movie made a deep impression, not only on me, but on the complete group of nearly 100 international experts on the topic of 'authentication' and provenance in Art.  The topic is about a private art collector in Indonesia, whose rather famous collection was being re-framed within the western discourse on 'authentication and value' and thus became a focus of controversy. 

Patricia Chen, in my opinion, was able to document this rather tragic process because she is not only a very interesting director, but also familiar with both Western and Asian ways of dealing with works that we consider to be art. Her movie is essential in two ways: not only is it an outsider’s view that enables us to reconsider the tragic way that we have fallen into traps that the art-market presents today, it has also brought Patricia Chen, as the messenger in peril herself; she has had to accept that her documentary was banned from its intended première in Singapore.

In both ways, I think, the representation of this documentary could be important for our reflection on the state of the current discourse on art in our own world, the discourse  is perverted, degenerated, and even poisonous as Patricia Chen shows us by her case study.

Speaker :  Singapore and The” Southeast Asian Art Ecosystem”


Singapore has since 1990′s stated its intention to position itself as a “global city for the arts”. However, discussions, published writings and specific decisions have, more often than not, been Singapore-centric, even though neither Singapore nor its arts scene exists in silo. The presentation proposed an alternative, outside-in approach in advancing this discourse. It framed the discussion by weaving in a broader framework that involves Indonesia and Hong Kong, through an overview of the Southeast Asian art market and comparative developments in the art scenes of Singapore, Hong Kong and Indonesia. Patricia took the audience through specific and detailed components that make up the Southeast Asian art scenes and markets, the workings of the validation and distribution centres before moving on to examine Singapore’s stated ambition and the issues that are associated with that aspiration – including that of education, mentality and attitudes as well as creative leadership. Perspectives from different individuals from within and outside the Southeast Asian art scene were also brought in to enrich the discourse and five filmed interviews were screened for the first time : T K Sabapathy, Art Historian (Singapore), Helena Spanjaard, Art Historian, (Amsterdam), Lorenzo Rudolf, Art Stage Singapore, Sylvain Levy, Collector, DSL Collection (Paris). A trailer for Leading Patrons of Asian Art also premiered that evening.

The Producer


Leading Patrons of Asian Art

This is the first dedicated project on significant patrons of Asian art, initiated to advance discourse on Asian art via the lens of art patronage. Through a series of films and publications that detail “closed-door conversations” with the personalities behind some of the world’s finest contemporary Asian contemporary and modern art collections, it is hoped that comparative accounts of Asia and Asian art can be brought on to a single ‘virtual’ platform. 

Core attributes of patrons for the project are as follows:

a. those who are forerunners of the art scene and preferably collected before the start of the art market;

b. those who have a predominantly Asian collection, preferably from a single scene;

c. those who were there preferably at the turn of the contemporary;

d. those whose collections have social values – the collections follow the historical development of the scene, and better still, if they can be accessible to the public;

e. those who are still active in supporting artists and defending the healthy development of the art scene today by organised activities and/or by implied attitudes in their actions or non-actions.


This is an independent project that started in 2011. The films received support from the Media Development Authority of Singapore and the Singapore Tourism Board. ​No collector funding has been received or utilised.
