Rosas Danst Rosas is one of the Belgian dance company's greatest hits and is still being performed around the world.

A spokeswoman for the dance troupe said they discovered the Beyonce video last week: "We noticed more than a few resemblances to the film. We have passed the details to our lawyer to see about our rights," she said.

Claiming legal ownership over a single dance move is difficult, although a sequence of moves could be protected if they were unique and the choreographer could prove they created them.

They would also have to show a substantial portion of the moves had been used without permission
