Those who've watched toxic bachelor Colin Farrell bloat out over the years might be as surprised as the man himself (judging by his sartorial slack) to see him now apparently wasting away. What gives? The Daily Mail snapped the 32-year-old swimming in his suit over the weekend.

Farrell has a rep for method acting—he beefed up for months to play Alexander the Great in 2004 and became a complete assbag in preparation for Miami Vice. He's currently shooting Triage, about a war photog on assignment in war-torn Bosnia in the early '90s, which could explain the weight loss. He also has a history with rehab. [Daily Mail]
