Colin Farrell, sporting a paunch and a mustache, was spotted filming The Lobster in Dublin over the weekend.

Farrell was on set Saturday wearing a gray suit and long thin tie while inhabiting his role in Yorgos Lanthimos’s The Lobster. Looking a bit softer than usual, the Irish actor was sporting a mustache, glasses and side part to complete his transformation.

Despite Farrell’s unassuming attire, The Lobster is actually a science-fiction film. In the film’s world, single men and women are given just 45 days to find a partner. If they don’t succeed, they risk being turned into an animal.

“It's one of the most challenging and different roles I've ever taken on,” Farell told Independent Woman IE.

If Farrell lived in the alternate universe of The Lobster, he’d likely be forced into finding a mate, as the 37-year-old actor is currently unattached.

“It’s as flat as ever, empty nothing,” told the Irish Mirror of his dating life. “I could throw a name out and it would come back to you, like a cave.”

Farrell costars in The Lobster with Rachel Weisz. John C. Reilly, Ashley Jensen, Michael Smiley, Jessica Barden, Ben Whishaw, Léa Seydoux and Olivia Colman are among the cast as well.
