Another One Bites the Dust
In the movie, there’s a scene when John Deacon plays the bass line for “Another One Bites the Dust” for the first time, he is seen playing a Sting Ray bass. This one is for guitar-heads: Deacon did really play this model at the time, but the movie shows a Sting Ray bass with a truss rod-adjustment wheel at the heel of the neck.
And this isn’t factually correct. In fact, the truss rod-adjustment wheel was introduced in 1990, which came all of ten years after the scene was supposed to be shot. So you can add that bit to the pile of factual mistakes the film made.
