ET found the stars of 'The Town' on the baseball diamond of one of Major League Baseball's most historic stadiums.

The movie is set in Boston and its premiere took place at one of the city's most iconic landmarks - Fenway Park.

Jeremy Renner's character in 'The Hurt Locker' may have been drawn to battle, but on Tuesday night Renner seemed to stray from unnecessary conflict. We asked the actor if he had a favorite team outside of the Red Sox. "No," said Renner, aware of the fervor that baseball fans in Boston have for their home team. "Are you kidding me? I don't want to get stoned."

Boston-native Ben Affleck directs and stars in the crime-drama and Chris Cooper thought that Affleck might see a few familiar faces in the crowd. "I imagine he's got a lot of friends out here," Cooper said of the fans present. "He deserves it. He turned out a really good film, I think."

Now, just how does one prepare for premiere at Fenway? We asked Jon Hamm. "I took a lot of batting practice, made sure my arm was nice and loose and I stretched," joked Hamm standing beside his significant other, Jennifer Westfeldt.

As far as the dress code was concerned, Blake Lively gave us the cardinal rule. "Don't wear your Yankees jersey, that's for sure," said the "Gossip Girl" star, acknowledging the long-standing rivalry between the two ball clubs.

The night was special for everyone involved but perhaps most meaningful for Ben Affleck, who visited Fenway with his father as a boy. "To me, you know, this is really the most special screening," Ben told us. "I've done a fair number of movie premieres and nothing's ever been special like this."

Affleck's good friend Matt Damon seemed to agree with him when he told us: "It doesn't get any better than this."

'The Town' hits theaters this Friday, September 17.
