Shrek, the beautiful green man, premiered at the 2001 Cannes Film Festival, where it competed for the Palme d'Or, making it the first animated film since Disney's Peter Pan (1953) to be chosen to do so. So obviously Shrek is what's up.
Shrek is an anti-social and highly-territorial green ogre who loves the solitude of his swamp. His life is interrupted after the dwarfish Lord Farquaad of Duloc unknowingly exiles a vast number of fairy-tale creatures to Shrek's swamp. Angered by the intrusion, he decides to visit Farquaad and demand they be moved elsewhere. He reluctantly allows the talkative Donkey, who was exiled as well, to tag along and guide him to Duloc.
Meanwhile, Farquaad is presented with Snow White's Magic Mirror, who tells him that in order to become a true king, he must marry a princess. Farquaad chooses Princess Fiona, who is imprisoned in a castle tower guarded by a dragon. Unwilling to perform the task himself, he organizes a tournament in which the winner will receive the "privilege" of rescuing Fiona. Shrek and Donkey arrive during the tournament and defeat Farquaad's knights. Farquaad proclaims them champions and demands that they rescue Fiona. Shrek negotiates to have the fairytale creatures relocated if he succeeds, and Farquaad accepts.
Also, this is only just the first movie, there are also three more movies to enjoy of the beautiful green man called Shrek!
