Mornflake has sealed a tie-up with Twentieth Century Fox that lets the cereal maker use images from smash hit Avatar on-pack.

The promotion, which marks the DVD and Blu-Ray release on 26 April, will appear on packs of Mornflake Chocolatey Squares from mid-April and will run for three months. Competition entrants have a chance to win a trip to the European Space Centre in Brussels or a Sony PS3.
