Bradley Cooper filming maserati the dark fields sunglasses

The other day we snapped Renee Zellweger's leading man on the set of The Dark Fields in Puerto Vallerta, Mexico, and it looked like the actor was having a blast filming a driving scene in a sexy black Corvette.

The psychological thriller doesn't hit theaters until next March, but we can't wait to see what the Hangover hottie brings to the table -- this is certainly a departure from all the rom coms he's been doing!
