Robert Pattinson doesn’t mind getting a bit weird for his movie roles.

Speaking exclusively to PEOPLE on the red carpet at the Mickey 17 world premiere in London on Thursday, Feb. 13, the 38-year-old actor playfully admitted that when he’s working on a new project, it sometimes leaves his loved ones with questions that need answers.

“I do a lot of wandering around kind of practicing stuff rather than practicing new characters, which annoys everyone around me,” Pattinson tells PEOPLE.

The Twilight alum adds that it’s not uncommon for those closest to him to ask questions like, “Why do you speak like a taxi driver in a German accent?”

Going on to praise Mickey 17, Pattison tells PEOPLE the movie was “one of the nicest, easiest shoots I’ve ever done in my life.”

“I think it was really complicated for everybody else,” he says, adding with a smile, “It’s easy for me.”

In the upcoming comedy sci-fi film from Parasite director Bong Joon Ho, Pattinson plays “unlikely hero, Mickey Barnes [who] has found himself in the extraordinary circumstance of working for an employer who demands the ultimate commitment to the job… to die, for a living,” per a synopsis.

“I’ve been the biggest fan of Bong for many, many years. He’s my hero,” Pattinson said at a surprise April 2024 appearance at CinemaCon in Las Vegas, according to Entertainment Weekly.

“I got sent the script; I was told, ‘You’re gonna love the script, but the part is impossible.’ That was very, very exciting to me. I thought it was the most unusual, bizarre, funny script,” he continued.

The new dad, who welcomed a daughter with his fiancée Suki Waterhouse in March 2024, also described his character as “someone who has the lowest expectations of his life, and yet the world keeps pushing those expectations, to the point where he has a job that tortures him every day.”

Things change when “18 comes along.” For Pattinson, playing the “out of control” character was “like playing an evil brother or twin.”

Mickey 17, which is based on Edward Ashton’s 2022 novel Mickey 7, also stars Steven Yeun, Naomi Ackie, Toni Collette and Mark Ruffalo.

The sci-fi film lands in theaters on March 7.
