Roberta: I think you'd agree with Roger Ebert, who says, in effect: don't remake a classic, remake a
near-classic. In other words, remake those movies that had some potential, but didn't quite make it, rather than remaking the movies that achieved perfection (or near-perfection) the first time around.
I'll give you one movie that, I think, could
benefit from a remake: "A Touch of Evil." There are a lot of people who consider this to be a film noir masterpiece, but I found it to be, at best, a terribly flawed masterpiece. The action needs to be tightened up, the script needs to be rewritten so that it makes sense, and someone with a believable Mexican accent needs to take the role that Charlton Heston played in the movie (memo to Hollywood: hey, how about Benicio del Toro?).
Some other remakes that were actually better than the originals:
"His Girl Friday" was better than "The Front Page"
Kenneth Branagh's "Henry V" was better than Laurence Olivier's version
and (I might get pelted with rotten fruit for saying this) "The Magnificent Seven" was at least as good, if not better than, "The Seven Samurai"
