With Baywatch releasing to theaters today, it seems appropriate to revisit the time Zac Efron took a header while filming a running scene for said movie. Efron can be seen in the before-and-after picture above running with the group then upside down on his head. Zac took the incident as humorous when it occurred and even tweeted out some of the photoshops below. Guy seems like a real chill dude I would love to have a beer with.
