Don't get me wrong, I really like the old versions, but some old movies seem dated and could use an update. Science Fiction and Comedies are probably the easiest to be remade, drama's are more difficult. Off the top of my head I can think of two. Forbidden Planet When Worlds Collide In regards to drama's, I could never imagine somebody trying to do a remake of films like, Casablanca, Bridge on the River Kwai or Lawrence of Arabia to name a few. If done right remakes can be good.
