Boom! There were some mighty big guns on the set of Scott Eastwood’s new movie – and not just the ones on tanks.
Clint Eastwood’s 27-year-old son, who created quite a splash after recently posing for a smoldering photo shoot in Town & Country, has posted a shirtless Instagram photo from the set of his movie Fury.
“Trying to out flex the tank. Not workin’,” the actor captioned the snapshot.
“People assumed that I would have everything handed to me, but that couldn’t be further from the truth,” he told Town & Country. “I was on my own just doing the grind.”
And, clearly, hitting the gym.
