That said, Ebert put it on his "Great Movies" list:

It's also possibly interesting for having had a 28-year old Truman Capote as screen writer. Except that I really think Capote wasn't a good fit for Hollywood. Breakfast at Tiffany's did not translate well to screen.
On the other hand, Roman Holiday is among my favorite films. It's the quintessential romcom.
For a terrific and unusual red-scare inspired film, let me recommend Johny Guitar. Now that's a film that deserves a cult following.
It's a pity they never even tried.
I thought it was okay. It was obviously toned down a lot from the book to meet then current sensibilities which would not offend an audience today. Ironically, there's a comedy bit with Mickey Rooney[2] that probably didn't offend American audiences at the time but that has not aged well. I also thought they added a bit too much slapstick.
