Sylvester Stallone is really the A-list actor who never should have been, but who we're glad was! Is... that even a complete sentence? Stallone got his start in the softcore porn flick The Italian Stallion (1970) where he showed off tip, taint, tush, and everything in between. This amazingly didn't TAINT his mainstream bankability, and in addition to making it big in flicks like Rocky (1976) and First Blood (1982), Stallone stripped down in a ton of other movies like The Specialist (1994), Demolition Man (1993), and more!
