Catch 22 was one of the best books of the 20th century.
It was also one of the funniest movies IMHO with an incredible cast of characters. Orson Wells, Bob Newhart, Alan Arkin, Buck Henry, Anthony Perkins, Martin Scheen, Norman Fell, Charles Grodin, Paula Prentise and Jon Voight.
Why would you want to do a remake? Of course, they made a remake of True Grit...
Living in the part of Oklahoma and having ancestors from Arkansas where True Grit took place I always had a problem with the first film. We don’t have snow on our mountains and the timber was wrong. Even though the second was made in Texas it at least looked closer to something like you might find where the story took place. You could take parts of both movies and have a pretty good film.
Film makers have been bowdlerizing and butchering literature from the beginning. I’m still waiting for true telling of Huckleberry Finn.
