The Red Sea Sharks: Part 2 - S3-E2
Continuity mistake: When the submarine fires on the cargo ship, Haddock yells "Full speed ahead" and pulls back the lever controlling the speed, but the lever snaps off, leaving it positioned at the SLOW sign, putting the ship in reverse. A few shots later, when Haddock puts a screwdriver against where the lever is place, it is suddenly positioned towards the HALF sign. (00:40:20)
