This month marks the 27th anniversary of the series premiere of "Seinfeld" on NBC, and to this day, its influence on the worlds of television and comedy remains unsurpassed.

The "show about nothing" was notorious for featuring up-and-coming actors in cameo roles over the course of its nine seasons, and a number of actors who played bit parts on the show eventually went on to become major stars in their own right.

Bryan Cranston ("Breaking Bad") and Jeremy Piven ("Entourage") both saw their stars rise in the years following their notable appearances on "Seinfeld," and many more now-famous actors benefitted from their brief moments in the spotlight on one of the most successful sitcoms in TV history.
