Can you really sue Fortnite for 'stealing' your dance moves?

The creator of the year's biggest game is facing a slew of lawsuits over its alleged use of famous dance moves. But will courts tap to the same tune?

Imagine it is 2014 and you are the rapper 2 Milly. You have just created a new dance for your music video Milly Rock, and it has proved wildly popular. Four years later, an extremely similar dance crops up in a globally successful video game with more than 200 million players. What do you do? What can you do?

The answer, of course, is sue. And that's exactly what 2 Milly, real name Terrence Ferguson, has done, alleging copyright infringement, having swiftly registered the Milly Rock dance with the US Copyright Office.
