This is in the scene in the restaurant, when Steven Seagal, is fighting many enemy's. Fast forward to the last enemy. The slip-up is when they are behind the bar. Put it in Slow Motion and watch Steven kick the enemy. After the enemy is kicked, he flys through the air, and his head is about to land right before the wall at the end of the bar. In the next frame, the entire guy falls through the wall that he just fell before.
