Colin Farrell and Allen Leech flew the Irish flag at the Screen Actors Guild Awards.
The actors both presented awards separately at the prestigious awards ceremony, which is often considered the biggest indicator of who will nab Oscars next month.
Leech has shot to international prominence thanks to his role in the awards season favourite The Imitation Game, alongside Benedict Cumberbatch and Keira Knightley.
And he was joined by his girlfriend of less than a year, Sky Sports presenter Charlie Webster for the occasion.
Meanwhile, Farrell avoided the red carpet and only appeared on stage to present the award for Best Supporting Actress.
While most of us eagerly await the second series of True Detective, it seems the show's true star is already clear - his moustache.
Um, is Colin Farrell intentionally paying tribute to the 'Mortdecai' moustache? #SAGAwards— BedheadatCB (@BedheadatCB) January 26, 2015
