Irish actor Cillian Murphy's performances in "Oppenheimer" and "Peaky Blinders" have been ranked as his most popular roles by a new study.

The study, commissioned by Betfair Casino, ranked Cillian Murphy's most popular performances based on IMDb, Metacritic, and Rotten Tomatoes ratings. 

Audiences were split between Murphy's performance in the title role of Christopher Nolan's 2023 summer blockbuster "Oppenheimer" and his performance as Tommy Shelby in the hugely popular BBC crime series "Peaky Blinders."

Meanwhile, his performance in the Ken Loach film "The Wind that Shakes the Barley" has been ranked as his third-most popular performance. 

Murphy plays Damien O'Donovan in the 2006 film, which won the prestigious Palme d'Or at the Cannes Film Festival. 

The film centers on two Cork brothers during the Irish War of Independence and the subsequent Civil War, pitting them against each other in heartbreaking circumstances.

His performance in the 2021 post-apocalyptic horror-thriller "A Quiet Place Part II" was named his fourth-most popular role in the new study, with his performance in "Cold Mountain," a 2003 film that follows a Confederate deserter toward the end of the US Civil War, completed the top five. 

"Sunshine," which takes place in 2057 and follows a group of astronauts working to save the sun, was named his sixth-most popular role, with comedy-thriller "The Party" taking seventh place. 

His performances in Irish films "Intermission" and "Breakfast on Pluto" also feature in the top ten in addition to the apocalyptic thriller "28 Days Later."
