There is one ironclad rule of Hollywood cinema: If your leading man has insane abs, you absolutely must show them off. However, there are some men who do it more than others and have become known as the great shirtless actors of cinema.
These stars aren't afraid to pop off their tops during a romantic moment, a shirt-ripping fight sequence, or even for just a bit of eye candy. Many are all but guaranteed to take off their shirts in whatever movie they're in. For some, it's an opportunity to showcase the results of all their hard work in the gym. For others, their shirtlessness is played up for laughs. There are also those rare few who integrate their disrobing into their ab-tastic characters so thoroughly it becomes part of the narrative.
Whether it's to play a bare-chested medieval fantasy warrior, a flawlessly toned American psycho, a dance-trained male stripper, or a charming yet mischievous surfer dude, there are a few Hollywood A-listers who seem downright allergic to T-shirts.
