Los Angeles, March 11 : Hollywood star Cillian Murphy was feted with the Oscar for best actor for Christopher Nolan's 'Oppenheimer' and he said that he is a 'very proud Irish Man' on bagging the honour.

Murphy played J. Robert Oppenheimer, the theoretical physicist and 'father of the atomic bomb' in the film and while accepting the honour, he thanked the Academy and Nolan.

'It's been the wildest, most exhilarating, most creatively satisfying journey you've taken me on over the last 20 years, I owe you more than I can say,' he said.

'Thank you so much (to) every single crew member, every single cast member on 'Oppenheimer,' you guys carried me through. All my fellow nominees, I remain in awe of you guys. Truly.'

Murphy added: 'My two boys, who are sitting up there, I love you so much, and I'm a very proud Irishman standing here tonight' We made a film about the man who created the atomic bomb, and for better or for worse, we're all living in Oppenheimer's world, so, I would like to dedicate this to the peacemakers everywhere.'

The film revolves around Oppenheimer as he grapples with the need to create an atomic weapon to counteract the German threat in World War II.
