Moviegoers were first introduced to Toni Collette for her breakout role as an ABBA-obsessed dreamer in the 1994 Australian flick "Muriel's Wedding," for which she gained 40 pounds! Since then, Collette has gone on to star in lots of movies including "The Sixth Sense," and currently appears on the Showtime series "United States of Tara."
