Last month, Ain't It Cool News announced a contest to "TRON-itize" vintage films. The idea is to take an old film and add CGI TRON-style graphics. Lots of entries have come in, but this is the best -- Charlie Chaplin's Modern Times, recut as a trailer for Modern Times: Legacy. It's short but effective. You've never seen The Tramp like this, folks.
And yes, I'm sure Chaplin's time-traveling extra will get a walk-on role if this film makes the cut.
If you want to see the source material for this, cheap out this clip.
