Shia LaBeouf and Jessica Chastain at NYC Lawless Premiere

Shia LaBeouf and his Lawless leading lady, Jessica Chastain, teamed up for a Cinema Society screening of their film at NYC's Paley Center for Media. The screening was also sponsored by YSL Beaute, and Jessica was fittingly decked out in a YSL dress with Tom Binns jewelry. She kept up her brand loyalty, wearing a black YSL outfit. In addition to Shia and Jessica, other stars checked out the premiere. Seth Meyers and Chloe Sevigny swung by, as did Patti Smith, Patricia Clarkson, and Melissa Leo. Later on, Shia and Jessica toasted their action movie, which is out Aug. 29, with an afterparty at Gallow Green at the McKittrick Hotel.

We caught a moment with both stars on the red carpet, and they spoke about how they stuck close to the film's Prohibition-era theme by drinking moonshine after the cameras stopped rolling. Shia viewed drinking as a good bonding experience with the cast, but Jessica didn't really take to it. She told us, "We would drink moonshine — I didn't drink so much moonshine. I like liquor that's sweet, and the moonshine we had down there wasn't so sweet!" Catch more from our interviews with both Shia and Jessica later today on PopSugar Rush.
