On Thursday, March 13, Reddit.com hosted an AMA (Ask Me Anything) with director Terry Gilliam.
Question: How do you feel about Zack Snyder saying he made Watchmen to “save it from the Terry Gilliams of this world”? How much pre-production did you do on the film before the project was abandoned, and what do you think of Zack’s adaptation?
Terry Gilliam: Charles Mckeown and I wrote the script. I always felt it was not the best way to treat it because trying to squeeze it into 2.5 hours is an unlikely thing. I think we wrote an interesting version of it, but I think it needed more time to really work. I thought Zack's film worked well, but it suffered from the very problem that I was happy to avoid by not making the film.
