The 'Harry Potter' lads are picking up their wands again. Domhnall Gleeson is not.

As some original Harry Potter stars return to the wizarding world, Domhnall Gleeson is perfectly happy to leave Bill Weasley in the past.

Last month, Rupert Grint announced that he will reprise his role as Ron Weasley in the Broadway production of Harry Potter and the Cursed Child , following Tom Felton's return as Draco Malfoy. But Gleeson, who portrayed the eldest Weasley brother in the final two Harry Potter films, isn't feeling inspired to pick up his wand again.

That doesn't mean he won't be cheering on his former costars. Gleeson saw Cursed Child in London's West End and expects Grint's Broadway entrance to be an unforgettable moment.

"It was fantastic," the Paper star tells Yahoo while promoting his new film, The Incomer . "The first time [Rupert] walks out onstage will be something else. … That's amazing that the lads went back to it."

But he won't be mounting a return of his own. Gleeson feels he has already had his moment.

"I got to do my bit," he says. "I'm happy with my lot. I feel good."

He is equally ready to pass Bill along when HBO's new Harry Potter series reaches the later books. The television adaptation , which premieres in December, stars Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger and Alastair Stout as Ron Weasley. Bill has not yet been cast.

As for what advice he would give his eventual successor, Gleeson believes the next Bill Weasley should make the role entirely his own.

"Good luck to whoever plays the part. They don't need any advice from me," he says. "No one owns those characters. It's their part now, so I wish them all the luck in the world."

That forward-looking attitude extends to Gleeson's career. Although he has appeared in blockbuster franchises including Harry Potter and Star Wars , he continues to gravitate toward smaller and decidedly stranger projects.

His latest, The Incomer , is an absurdist folk comedy about two isolated siblings (Gayle Rankin and Grant O'Rourke) defending their remote Scottish island from Daniel (Gleeson), an awkward council worker sent to relocate them. It's in select U.S. theaters on Friday.

For Gleeson, a project needs to feel unfamiliar — or even a little intimidating — to get his attention.

"It has to feel a little bit new, like you haven't done it before, or a little bit scary in some way," he explains. "Now I'm just looking for stuff that I feel that I can connect with and that other people will be able to connect with, if we can find the audience."

Despite not being a traditional feel-good movie, The Incomer left Gleeson unexpectedly uplifted. He was particularly drawn to Daniel, a man who has become "sort of a wallpaper person" on the mainland but hasn't given up on finding purpose or connection.

"It doesn't mean that he doesn't have something to say or that he doesn't matter," Gleeson says. "Then he meets these two people who don't care what anyone else thinks, because they don't know anyone else. I thought that clash was really great."

Daniel isn't the only lonely man seeking connection on Gleeson's résumé lately. A recent IMDb credit is literally "Lonely Man" in Taylor Swift's "Opalite" music video. So, I ask, is he in his lonely-man acting era?

"Oh my God, what a horrible thing to think of," he laughs. "As long as the lonely man is trying to connect, then that's the journey I'm interested in. So, yeah: Lonely Man seeks connection."

It's a tough sell in real life, he quips.

"It's not the greatest Tinder profile. 'Lonely Man' probably doesn't get all that much interest," Gleeson says. "But he's worth rooting for. I think that's all that matters."

Gleeson has warm words for Swift, who put him at ease during the two-day shoot.

"Everything I had hoped for, she was — and more," he says. "She was incredibly collaborative. She was fun: just fun, fun, fun. ... I was nervous about the dance and all this sort of stuff, and she just made it fun."

That joy, he believes, is visible in the final product.

"I think you can feel it," he says. "It's similar with The Incomer : When you can feel the joy in something, it really translates. In the 'Opalite' video, that's absolutely there."

Gleeson hopes audiences will discover that same spirit in The Incomer , now and in the years ahead. He points to his beloved 2013 romantic comedy About Time , which continues to find new audiences more than a decade after its release.

"It's grown and grown and grown as the years have gone on," he says. "Lots of young people like it, and it means a lot to people in the way we wanted it to mean something to people. It's a beautiful thing."

Seeing the film endure — thanks in part to Rachel McAdams and Bill Nighy's performances — has only encouraged Gleeson to keep pursuing meaningful work.

"It just makes you want to keep on doing the good stuff," he says.

He believes The Incomer could enjoy a similar life.

"I feel like this is a film that will grow and grow and grow as the years go on," he says. "But I'd also like people to see it now."
