When Lance is escaping from his hotel room, he swings out the window holding on to the drapes. When the scene cuts to a close up of him climbing back up the wall to the window he is clearly gripping a black woven rope, not the drapes. When the shot changes again he's beck to holding the drapes.
When Lance is hanging on a car, hockey players who are after him break the woman's back window but when Lance falls off her car, and she drives off, her back window is fine.
Lance finds a super soaker imitation water gun, and he wants to fill it up with flammable liquid. Instead of taking off the removable tank, and putting the liquid in there, he instead pulls the bottom part, and sucks the liquid into the gun from the front of the gun. This is not the proper way of filling up this type of water gun.
