Yeah they did a lot of weird things. Like Keira Knightly's character Joan Clarke gets her job in the film when Turing does his weird crossword puzzle test. In real life she got it because one of her professors from school recommended her for the job. In the movie Turing works closely with Cairncross and realizes he is a Soviet spy. In real life while they worked at Bletchley park there is no evidence they ever met. It also really downplays the role Polish intelligence and cryptanalysts had in breaking Enigma from before the war even started.
