The star reprised her role as Marie and her alter ego Rogue to reunite with castmates from the original X-Men trilogy, Hugh Jackman, Sir Patrick Stewart and Sir Ian MCKellen, for a brief appearance in director Bryan Singer's new installment, X-Men: Days of Future Past.
However, Singer has since revealed the final cut of the movie will not feature Paquin's character after all.
He tells Entertainment Weekly, "Through the editing process, the sequence became extraneous. It's a really good sequence and it will probably end up on the Dvd so people can see it. But like many things in the editing process, it was an embarrassment of riches and it was just one of the things that had to go.
"Unfortunately, it was the one and only sequence Anna Paquin was in, the Rogue character was in. Even though she's in the materials and part of the process of making the film, she won't appear in it."
The film is due for release next year (14).
