Flashback Friday: Tom Cruise Sings in His Underwear for 'Risky Business' (VIDEO)
In the classic '80s flick Risky Business, the actor played a precocious high schooler by the name of Joel Goodsen who gets rowdy when his parents leave him home alone. To celebrate his independence -- and manhood -- he strips down to his briefs and lip-synchs to "Old Time Rock and Roll" by Bob Seger.
See how Cruise became a Hollywood hunk by watching the Risky Business clip above, and watch the clip below to see the now-50-year-old in Jack Reacher.
