I have just seen the film for the umpteenth time and of course the facts as portrayed in the film are not always a true reflection of the actual reports of the raid. Incidents that are shown as the interior of a submarine that was destroyed can be nothing other than fiction. Some of the episodes were factually correct therefore I find that the comment by mailmartinbuckley regarding the scene where Donald Sinden fends off a mine with his feet was misplaced. It was a recreation of the incident where Lt.B.C.G Place from X7 did exactly that. If he refers to bbc.co.uk/history and enters "Tirpitz" he can read the account of the raid by Dr.Eric Grove, a naval historian
