X-Men: The Last Stand DVD: Easter Eggs

Choose 'Scene Selection,' go to Scenes 10-12 and press DOWN. The logo will take you to a Deleted Scene where Beast recites Shakespeare.

Go to the "Deleted Scenes." On the Fourth screen in the upper left-hand corner is the Mutant Mark (or an X in the Brotherhood Menu). Move the cursor UP and the symbol stops lighting up and the cursor disappears. Click "OK" and it takes you to a pre-production scene. Then select 'Play.'

On Disc 2 go to the "Galleries" then "Character Stills." Once there, on the top right you will see a Triangular symbol. CLICK it for the blooper.
