Actor-turned-director Mel Gibson has tricked fans by making a surprise cameo in the trailer for his new movie APOCALYPTO.

Eagle-eyed American film fans have spotted a fleeting appearance by the LETHAL WEAPON star in the promotional advertisement which is currently playing in cinemas across the US.

The action movie, set 600 years ago in Mexico and filmed entirely in local language Mayan, is released early next year (06).

Master film-maker Alfred Hitchcock famously took cameo roles in each of his movies.
