I remember reading that there was talks of a remake of "Butch Cassidy and the Sundance Kid", with John Travolta and Tom Cruise as the leads (don't know who was going to be whom). Thankfully I haven't heard anything since.
There have been plenty of good remakes, even of classics. Some often better than the original. "Butch Cassidy and the Sundance Kid" is, in fact, a remake (the original starred the Skipper from Gilligan's Island). "Dirty Rotten Scoundrels" is a remake. "Cape Fear", "3:10 to Yuma", and "Scarface" are all remakes.
Then there's the adaptation remakes, like "The Magnificent Seven" ("Seven Samurai"), "Fist Full of Dollars" ("Yojimbo"), and "The Departed" ("Infernal Affairs"). It's hard to choose a favorite, as both the originals and the American adaptations are fantastic.
Usually I don't like it when a classic movie gets remade, but the exceptions can be sci-fi/fantasy movies. A good sci-fi story will hold its significance, but the nature of unpredictable technology has made many "classics" completely dated.. "Alien", for example is a classic, but the computers are laughable. It's hard for the new generations of film viewers to appreciate these classics when the "technology" undermines the movie. Ditto "2001", "Logan's Run", "Blade Runner", and such. Some obviously should remain untouched, but every 25 years or so, a good sci-fi story can be due for a remake. Look at all the different movie versions of "I am Legend".
That's why I'm so torn about the remake of "Total Recall". The original with Ahnold is a classic. Most people think it's just some 1980's uber-cheese, but those people don't get the movie at all. Sure it's got some classic cheese in it, which brilliantly belies the typically ambiguous Phillip K Dick story. This remake (starring Colin Farrel as Quaid/Hauser) obviously won't have the cheese, so what's left is the story. If they can keep the story the way it's supposed to be, it could be good. But the prior credits of the director and the screenwriters on the remake don't leave me with much confidence. I have a feeling they'll dumb down the story and make it Hollywood, as audiences these days are easily confused and don't like it when they have to think to much. If only they could have gotten Christopher Nolan to direct it. I'll be the first to praise them if they do it justice, but I'll also be the first to gripe if they screw it up.
