After challenging an evil dragon, rescuing a beautiful princess and saving your in-laws' kingdom, what's an ogre to do? We find out next Summer when the fourth instalment of the Shrek franchise is released worldwide. Starring the vocal talents of Mike Myers, Eddie Murphy, Cameron Diaz, Antonio Banderas and, funnily enough, Paul McCartney, this latest adventure sees Shrek try to rediscover his primal ogre ways having ended up as something of a domesticated family man. Not content with this life in the rat race, Shrek is tricked into a pact with the smooth-talking troublemaker, Rumpelstiltskin. Unfortunately this pact backfires and Shrek is whisked away to an alternate reality where ogres are hunted and he's never met Fiona, his one true love. Can Shrek undo all he's done in the hopes of saving his friends and restoring his world?
