Highest box-office film gross for an actor (average per film)

When trying to maintain the highest possible average per film gross at the box office, agreeing to appear only in guaranteed blockbusters would seem to be the key. This is well demonstrated by the success of the Harry Potter franchise, which allowed five young actors – Matthew Lewis (who played Neville Longbottom), James Phelps (Fred Weasley), Oliver Phelps (George Weasley), Bonnie Wright (Ginny Weasley) and Josh Herdman (Gregory Goyle) – to jointly claim the highest average box-office gross ever achieved by an actor. By appearing in all eight instalments of the Potter series (released between 2001 and 2011), with no other screen roles to date, they have each achieved a total worldwide box office gross of $7,709,205,984 (£4,795,126,122) – an average of $963,650,748 (£599,390,765) per film. If we discount actors associated with the Harry Potter franchise, the highest per film box-office average belongs to Sam Worthington, whose 13 film roles to date have achieved an average gross of $313,716,697 (£195,131,786).
