We've had best line, worst line, best scene, best soundtrack, now we shall discuss movie bloopers. Why? Becasue I said so.
For me, the most standout blooper is in Braveheart, in the Battle of Stirling scene, when the Scots charge. Wallace goes from an axe, to nothing to a sword to the axe again and then pulling out the sword. Its so bloody noticeable you wonder how it was picked up during the editing process.
Oh and of course, who can forget the stormtrooper hitting his head on the door in A New Hope.
