Everything you need to know about Northern Ireland-born actor Aaron McCusker.

"Shameless" star Aaron McCusker plays the role of Jim Hutton, Freddie Mercury’s partner in the biopic “Bohemian Rhapsody”.

While Hutton is given little prominence in the film, the role in one of the most talked about movies of the year is a major coup for McCusker.

The 39-year-old thesp plays Hutton, a hairdresser from County Carlow who was a key figure in Mercury’s life. The couple were together for six years before Mercury’s AIDs-inflicted death in 1991.

Bohemian Rhapsody doesn't actually cover his relationship with Jim Hutton, his husband (Freddie called him as his husband); Was I disappointed? Yes. But we got to see Jim Hutton in few scenes, you can entirely see that their relationship is going to be a Beautiful Relationship - pic.twitter.com/isgmbnqo47
