Is this football play from the movie "The Waterboy" legal?

It is a legal move, the defensive lines can shift so long as they don't encroach the line of scrimmage. The offensive line however is not permitted to move once they enter the the three point stance. This move however is easily counterable via a simple roll out by the quarterback in the other direction or a run to the opposite side and would quickly be audibled against in a pro game.
