If you're talking Imitation Game, then Polish involvement was mentioned in passing (a single sentence - I'd been looking out for it), but yes, the whole thing was very fictionalised, and tried to paint Turing as a single genius maverick against the system, rather than providing the next evolution in a process that had begun before him, and continued with others, so it ignored a lot of other people, including many of those at Bletchley as well as the Polish work.

Never let the truth get in the way of a good story.
