When it comes to practical effects, Christopher Nolan’s new film The Odyssey is no joke. Matt Damon’s biceps on the poster are actually Devyn Dalton's – a 4ft 6in Canadian actress with some seriously impressive arms.

Damon revealed in an interview that his double was a female stunt performer whose ripped physique made her the perfect stand-in during a scene where Odysseus and his men face giants. Since Damon’s comments went viral, Dalton has been enjoying huge global attention. “Apparently my biceps have their own fanclub right now,” she told The Guardian.

The revelation highlights Nolan's commitment to traditional filmmaking methods over CGI. It’s a win for practical effects that mirror real-life feats in the movie industry.

This isn't just about physicality, though; it's also a nod to the underappreciated work behind the scenes of blockbuster films. Dalton's story is an inspiring tale of how talent and determination can shine through even when you're hidden from public view.
