TCM is owned by Time Warner. Organizers can't just screen things and charge a fee without the owner/studio's permission. The rumor is we'll see something in the fall.
Because they have already been gathered and shown in one place. On April 24, 2010, a total of eight of the Censored Eleven were screened at the Egyptian Theater in Hollywood. It was part of the TCM Classic Film Festival.
As most of you know, back in 2010 we were suppose to see a BD WAC release of the censored 11 cartoons. It's 7 years later and nothing... Hopefully this will actually pan out.
