Character mistake: In the shot of Gordon pulling Percy, he is congratulating Percy, but Percy didn't stop the accident, Gordon himself did. Percy didn't try to get out of the way, Gordon had to put his brakes on as hard as he can. So why is Gordon congratulating Percy?
Revealing mistake: When Gordon is being pulled from the pond, in the close up scene of Gordon reversing up the sleeper bed, the front of his buffer beam/running board catches on the upright stake to the right hand side of the worker figure, pulling it back before it rights itself. (easier to see on widescreen version).
