When Ace goes to the shark tank, at the end of the Mission Impossible music, he gets inside from a door (duh). If you look at the take right after when Ace is inside, you see him making the move of closing a door, you hear the noise, but there's no door.
If you pay attention, on Ace's right is where the door is. There is a wall blocking the door. He does this little spin move so you may have to rewind a few times to see it, or to get it. I did, but the door is there.
The original poster is correct about there not being a door. Ace makes the motion of closing the door in the air but there is none.
More proof of Ace not being in the same location after entering the door is the plant against the wall. It is against the wall when he opens the door but is no longer there when he fakes closing it.
