I'm typically against remakes, but there are some that occasionally come out that are done really well. True Grit comes to mind recently but I'm sure I could think of others.
So, what are some that you would choose?
One that would be interesting to see done with more modern technology is Blade Runner, although as it's one of my favorite sci fi movies I'd be nervous about how it'd come out.
Another that could be interesting is The Grapes of Wrath. The Henry Fonda movie from the 40s or 50s is a classic-ish, but I think that a current director could do this book-to-movie translation amazingly. Same goes for Steinbeck's other classic, East of Eden. The James Dean movie really was only a cursory translation of the book, so I'd love to see someone do the story justice.
