I haven't seen the film, but the description does seem like a galliard, or possibly its faster, closer to the ground dancealike, the tourdion. The likelihood of getting a historical dance right in a film is extremely low. I've worked on film sets playing historical music for dancers, and the truth is that actors are actors, not dancers, so on a tight schedule the choreoghrapher is working with the art of the possible, not the accurate, and it's improbable that anyone on set cares about historical accuracy. If it matters, Queen Elizabeth I will not have danced La Volta in public, despite the rumours and the paintings purporting to show her doing so, for reasons explained in this article.
