Mistake in film

Rating: 2/10 (20 February 2006)

As The French are digging in the sewers a big mistake in continuity occurs.
They have been digging in the sewers under the team bath.
My first query is how do they know they are under the correct dressing room and not about to break into a room full of Germans? They do miraculously dig into the correct bath.
Which is very full.
They break through the floor, and the water pours out the hole in the floor.
The guy at the top of the ladder is barely wet but that's not the mistake.
The walls of the tunnels where the water just fell through as they go down the ladder are bone dry, as is the ladder.
Someone forgot about the water they just released.
Idiots.
