Jon Favreau tweeted a link to a cool new commercial he directed for 5 Gum. I actually saw this commercial recently but had no idea Favreau directed it until his tweet went out to the world. The commercial turned out to be pretty bad ass. It features Daniel Ilabaca doing what's called parkour, which is that crazy cool sport of running, jumping, and flipping through city obsticles. Check it out below, and tell us what you think!
