Cillian Murphy has a genius hack for going to movie theaters without getting recognized by fans

• Cillian Murphy told the Los Angeles Times that he went to see "Barbie" in a theater in Dublin.
• Murphy said that he's devised a strategy to avoid getting recognized at the movies.

"Oppenheimer" star Cillian Murphy figured out a genius trick to avoid getting spotted by fans when he visits movie theaters.

"I time going to movies very well now," Murphy, 47, told the Los Angeles Times in an interview published Tuesday. "With the ads and trailers, I always arrive a half hour late, slip in and then slip out."

Murphy's comment was prefaced by reporter Glenn Whipp asking the actor how he managed to watch Greta Gerwig's "Barbie" in his home city of Dublin earlier this year without causing a commotion.

Murphy, who's been acting professionally since the '90s, is known for roles in "Peaky Blinders" and several of Christopher Nolan's films — in addition to his signature piercing blue eyes. In recent months, he's garnered critical acclaim for his performance as real-life American theoretical physicist J. Robert Oppenheimer in Nolan's "Oppenheimer."

"Oppenheimer" and "Barbie" — collectively known as "Barbenheimer" — were both released on July 21, spawning a box-office rivalry and pop culture phenomenon.

Murphy voiced his support of "Barbie" during an interview with IGN that month and said he was definitely planning on seeing the movie.

"I think it's just great for the industry and for audiences that we have two amazing films by amazing filmmakers coming out the same day," he said. "You could spend a whole day in the cinema, what's better than that?"

He shared similar comments about the moviegoing experience in his interview with the LA Times. "To be part of a movie that people went to see multiple times and part of a great moment for cinema, that frenzy for those two films, was just lovely," he said. "I don't know if we'll ever see it again, but I'd like to hope so."
