The Day the Clown Cried (partially found unreleased Jerry Lewis film; 1972)
In 1971, Jerry Lewis and Nathan Wachsberger began producing a film titled The Day the Clown Cried, which was quite controversial due to its content, that being of a clown who becomes a prisoner of war in a Nazi concentration camp for speaking badly of Adolf Hitler.
Despite only having been seen by a handful of people, the film's dark and tragic plot and premise brought a lot of attention to the film. The script was originally written in 1962 - nearly a decade earlier - by Joan O'Brien and Charles Denton, although it was eventually re-written from the ground up by Lewis prior to the beginning of the film's production.
Production of the film was riddled with issues, a big one being that the budget for the film ran out before its completion. A feud ensued between Lewis and Wachberger, which ended with Lewis taking a copy of the film so that it wouldn't be lost, and Wachberger keeping the original negatives, planning to finish the film himself. Nothing ever came from Wachberger, but Lewis continued working on the film, stating in 1973 that the film was in final production, and had even been invited to play at the Cannes Film Festival, after which time it was to be released in America. To this day, the film has not been released, and has become somewhat infamous among film buffs/historians.
In 1979, comedian Harry Shearer was shown a rough cut of the film, later recalling the film in a 1992 magazine article and saying "with most of these kinds of things, you find that the anticipation, or the concept, is better than the thing itself. But seeing this film was really awe-inspiring, in that you are rarely in the presence of a perfect object. This was a perfect object. This movie is so drastically wrong, its pathos and its comedy are so wildly misplaced, that you could not, in your fantasy of what it might be like, improve on what it really is. 'Oh My God!' – that's all you can say."
Several screenshots from the film and photos from the set have surfaced, as well as a early draft of Lewis' re-written script from 1971, a brief behind-the-scenes clip and, most recently, a half-hour Flemish behind-the-scenes documentary on the production release in 1972, featuring actual takes of a scene from the film, one of which would have presumably been used in the final product.
Release of the Film
In 2001, while giving a motivational speech, Lewis was asked about a potential release for The Day the Clown Cried, replying "none of your goddamn business!". However, when asked the question again by an audience member during a live 2013 interview, he revealed that the film would never receive a release, the reason being that he was embarrassed by how it turned out.
French film director Xavier Giannoli publicly revealed in 2012 that he is in possession of an incomplete (1h 15m) 35mm copy of the film and has stated that he has held a few private screenings of it, perhaps most notably for French film critic Jean-Michel Frodon, who wrote about it in his 2013 publication The Last Laugh: Strange Humors of Cinema.
In 2015, the LA Times reported that a copy of the film had recently been donated to the Library of Congress by Jerry Lewis, but with the condition that the film not be shown for 10 years. 
On February 3, 2016, German public TV ARD aired a 2-hour documentary called "Der Clown". German film maker Eric Friedler shows interviews, original footage and re-staged scenes from the original scripts with some Swedish actors who participated in Lewis' movie. Finally, the film shows the first full interview with Lewis about his work after 43 years. Later in February 2016, the discovery of an unfinished documentary by Traces Films was mentioned in several relevant YouTube comment threads. The documentary makers are Australian based and posted a six minute teaser in 2012 which includes exceptionally candid and emotional interview excerpts with Jerry Lewis discussing his involvement with making The Day the Clown Cried. The documentary makers have refused to make any detailed comment other than state the film has reached a critical juncture in its production process.
On June 16, 2016, roughly 30 minutes of footage from the film was discovered on Vimeo. The footage included dubbed film scenes from a German documentary about the film, while other sections were filled in with title cards as well as certain scenes from Patton Oswalt's live staging of the script. Despite all the missing material, it’s far and away the most comprehensive assemblage yet seen of the project, and while the original video has since been deleted, it has since been re-uploaded to other sites.
