If you go through some of the best actor's in Hollywood's profiles you'd be amazed at how many dropped out of highschool to persue acting and have made a nice career out of it.
Of course, if you don't have talent that will make up for your lack of finishing highschool..you probably should stay and finish. Unless you are some freakish talent like Mario or the next great Hollywood actor.
