Austin Swift On His Journey to Becoming a Leading Man & the Best Advice Taylor Gives Him (Exclusive)

The actor also shared what he learned from Ben Affleck and Pierce Brosnan at the premiere of his new drama, 'Cover Versions,' which is available on digital April 10.

Austin Swift continues to make his mark in Hollywood.

The 26-year-old actor, who takes a leading role in his new movie, Cover Versions, talked to ET's Keltie Knight at the film's premiere on Monday night, where he shared what he learned from his early acting gigs alongside stars like Ben Affleck and Pierce Brosnan.

“I think the biggest thing you learn from seeing them work is how good they actually are and how great they actually are,” Austin said. “You learn to aspire higher than you thought you had to. You aspire to be that good and that capable. [I tried] to bring a little bit of that to this one.”

Austin made his film debut in the 2016 Pierce Brosnan mystery drama A.I., then appeared opposite Ben Affleck in Live By Night.

Cover Versions sees four band members recounting a night of debauchery before their first major gig at a music festival. Austin stars alongside former Nickelodeon star Drake Bell, Arrow’s Katie Cassidy and Disney star Debby Ryan in the film.

“It was awesome,” Austin said of the tight friendships the cast formed. “Most of the film was all shot at the same location [so we just] showed up to work every day, made a movie, hung out and had fun.”

“Debby is incredible,” he added, when quizzed about his gorgeous costar. “It is so fun to work with her and she’s so knowledgeable. It was great to work with her.”

Austin has also filmed the comedy, Whaling, with Harry Potter and the Sorcerer’s Stone star Tom Felton and Pretty Little Liars’ Tammin Sursok.

In addition to his big screen projects, he has cameoed on the television series, Still the King and Embeds, but it’s movies he hopes to continue making. “Absolutely -- fingers crossed,” he told ET.

Meanwhile, one person Austin has the full encouragement of on his acting journey is his pop star older sister, Taylor Swift. During the interview, Austin revealed the advice the Reputation singer gives her brother to keep him motivated to pursue projects.

“[I get] a lot of advice in all aspects, but I think the best advice I get from Taylor is that she says I can do things -- in the sense that a lot of times I’m more reserved and cautious and she’s like, ‘You can do it, you can handle it,’” Swift told ET’s Keltie Knight at the premiere of the film in Los Angeles, California, on Monday. “That’s always nice to have that in the background.”

Cover Versions is available on digital on April 10.
