The top mistakes in Deathwatch http://www.moviemistakes.com/film2940 en Sat, 04 Feb 2012 06:56:36 +0000 20357 The rifles the British soldiers carried in the film were Lee Enfield rifle No.4's, these did not go into production until WW2. They should have been using an earlier version of the Lee Enfield rifle. 155054 Tate refers to McNess as a "plank". The first recorded use of "plank" to mean "idiot" wasn't until 1981. 155053 Steel helmets were introduced into the British Army in 1916. After their introduction no soldier would have gone into the front line, and certainly not over the top, in a peaked cap, as several of the soldiers do (the film is set in 1917). 155052 One of the soldiers says that it isn't a holiday camp. Holiday camps were not introduced until the 1930s, over a decade after the film was set. 155055 Captain Jennings is referred to as the CO (Commanding Officer). In the British Army only battalion and regimental commanders are referred to as COs. Company commanders like Jennings are OCs (Officers Commanding). Not a mistake any British soldier is likely to make.
