One movie I wouldn't mind a remake of
I love the original. It's got some great effects (the fireball, the view of the black hole from the Signus bridge), Dante's Inferno ties in well, and the score is incredible.
However, now that more is known about black holes, I think it would be interesting to see a remake that delves into the science aspect a bit more. Keep the score, keep the Inferno bits, but delve into the science vs. religion idea and the theories about what is on the other side. Tie in with some sweet action sets and a new design for Maximillian, and I think it would crush it at the box office.
