In Tron: Legacy, Jeff Bridges is digitally manipulated to look like his younger self, and many critics — and even the film's own director — have felt like it doesn't quite work. But even though groundbreaking technology was used for this misfire, the filmmakers can rest easy knowing that they're still part of an age-old tradition.

So to celebrate the opening of Tron: Legacy, we've selected what we think are the eight worst aging jobs: four flash forwards, and four flashbacks. And as always, let us know which ones you think should have made the bad timing Hall of Fame.
