Shirts off, boys! These loincloths leave very little to the imagination – and we’re not complaining. There’s nothing cold-blooded about Twilight star Kellan Lutz, 25, in his upcoming film Immortals – he may still look a little pale, but with those abs, he’s packing major heat.
He’s not the only star going back in time for his fashion cues. Jake Gyllenhaal, 29, bulked up for his role in last month s Prince of Persia: The Sands of Time, and from the looks of it, his hard work(outs) paid off.
Remember when Brad Pitt rocked a similar look? The actor, 41 at the time, played Achilles in 2004’s Troy. Sam Worthington, 33, also shed most of his clothes (nice breast plate!) for his role as Perseus in the 2010 movie Clash of the Titans.
Sharpen those swords – it’s going to be a chest-off!
