26. 1993: 'Groundhog Day'
Groundhog Day isn't one of those movies that would be hard to remake - it's a feel-good comedy about a grumpy weatherman that has to lower himself into doing a puff piece about a groundhog. But the cast was so iconic that it would be a sin to try to recreate. From Bill Murray's iconic performance as Phil, to Ned the insurance salesman's chipper and annoying sales pitches, to Phil's slow-simmering relationship with Rita (portrayed by the wonderful Andie MacDowell,) it can't be touched.
