Log Rolling Sequence … Brent (doubling Owen Wilson) and Jackie are on top of some 40 logs chained to the flatbed car of a train moving at 30mph. The chain is loosened causing the logs, each weighing 1500 lbs., to roll off the car, down some 60 – 70 feet below. Brent and Jackie stay on top of the logs by logrolling. After the last log drops, Jackie jumps off to the car and Brent settles to the deck.
