U-571 (2000)

Character mistake: After accurately depth charging U-571, the German destroyer crew suddenly turns out to be almost comically and unrealistically incompetent at the end of the movie. Not only do they barely hit U-571 with their guns, but they also can't keep up with the sub. But even with both submarine diesel engines running flank speed (of which U-571 only has one badly damaged engine operational), a common WWII destroyer would easily be twice as fast as a Type VII U-boat. The destroyer could swiftly close the distance and could either ram U-571 or cross the sub's wake to bring all its weapons to bear and make it more difficult to get hit by the sub. Of course the destroyer doesn't do that but stays perfectly in U-571's wake for an easy kill shot from its stern tube. In reality, it was considered an incredible feat to sink a destroyer with a torpedo, since they were agile at full speed, could easily dodge torpedoes and had shallow draft. This destroyer crew however, seems actively trying to get killed.

Lieutenant Andrew Tyler: What the hell are you doing, huh? This is not a God damn democracy.

Trivia: U-571 cause quite a stir in England especially in the small northern town of Horsforth (where I actually live), because we felt the movie 'Hollywood-ised' a British victory. The people of Horsforth raised an astonishing £241,000 in one week (about £4million today) to fund the building of the HMS Aubretia, the ship that captured the first enigma machine when it depth charged U-110. It caused so much upset amongst people that President Bill Clinton wrote a letter to the people of Horsforth praising the town for their part in the war effort. The letter is now on display in the local museum.

Question: Throughout the film you can see that Tank, played by Dave Power, has funny-looking thin black scars on both cheeks. Was this a makeup effect for the character (and if so, why did they do it), or does the actor really have these scars on his cheeks (and if so, what from)?
