James Franco shares a picture of him as Tommy Wiseau for upcoming movie

The Room, a film funded by "entrepeneur" Tommy Wiseau for $6 million, was supposed to be a serious movie, but what turned out instead was, what many consider, one of the very worst movies of all-time. 

Wiseau wrote, directed and financed "The Room" back in 2003, a film so bad that it has transcended genres and is now known as a "cult comedy." The film was so fascinatingly inept that it seemed too good to be true. Were Wiseau's intentions genuine? Did he really set out to make a good movie? The answer, we found out, was, quite certainly, yes.

The dialogue was the stuff a third grader would write, the performances wooden and the sex scenes some of the most howlingly funny in cinematic history. Little did we think that Wiseau would ever want to make another film after his first catastrophic effort, but if there is anything that sets Wiseau apart from the rest it's his undying and overtly relentless passion for moviemaking.
Its incomprehensible narrative, terribly disjointed script, and hilarious non-intentional acting has been the joke for of many since its 2003 debut.
It has become such a cult classic that there are countless nationwide screenings out there of the movie. If there is one in the area I do recommend you experience a sold-out showing of the film, the hoots and hollers alone are worth the price of admission.

"The Masterpiece" could become a cult classic of its own as it is a behind-the-scenes look at the making of Tommy Wiseau's 2003 abomination.  The film stars James Franco, Dave Franco, Seth Rogen, Alison Brie, Zach Efron, Sharon Stone, Melanie Griffith and, yes, Bryan Cranston as himself.
