Sullivan's Travels is one of my absolute favourite films. Its on Sky Cinema 1 today at 09.10am and 6.25pm. They often repeat films for a few weeks but can't see it again this week.
If you like the Coen Brothers' "Oh Brother, Where Art Though" (and I don't!) you'll find this very interesting as OBWAT is FULL of references to Sullivan's Travels.
Happy watching!
