These women captured one of the scariest scenes from The Shining, as they dressed up as the twins from the horror classic complete with bloodied skirts, an axe and a picture of Jack Nicholson in his most famous scene.

It was one of the biggest superhero movie hits of this year, and there were plenty of people showing their appreciation for Deadpool.

Wonder Woman is always a popular choice at the convention too.
