I know I have to run 20 more minutes if I eat ice cream. Basically, I eat everything, but I just do more training.
My schedule goes: wake up, running, exercise, downstairs, running shoes off, then to the shower. That's the Jackie Chan diary.
One thing I did pick up from Cannonball Run was the use of bloopers and outtakes under the final credits, which I've done in all my movies since.
