The Irish actor plays the role of Percival Graves, the director of security at the Magical Congress of US, in the eagerly awaited-new movie, which is based on J.K. Rowling's book by the same name.

Farrell shared that he has never read Rowling's most popular books but is a self-confessed fan of the "Harry Potter" film series, reports femalefirst.co.uk. 

"There are a few films where in they're on the television, I just can't turn them off, they're just so comforting and any 'Harry Potter' series qualifies as one of those films.

"It's just such a beautiful and immersive world, that pays due respect to human emotions. I would be a liar if I said being in a trailer where that score kicks in didn't get me excited. I'm 40 and I shouldn't say such things," Farrell told SFX magazine.
