Rose Byrne will reprise her role as Moira MacTaggert in X-Men: Apocalypse.

According to Entertainment Weekly, she will join Jean Grey, Cyclops, and Storm, who will also be reintroduced into the hugely successful Marvel Comics' franchise.

Apocalypse writer Simon Kinberg said she will have a significant role in the film. "We ended First Class with Charles having wiped portions of her memory of her experience with the X-Men. They are, essentially, strangers to her when she meets them," he explained.

Kinberg also teased a possible Professor X plot, saying: "It's certainly a rich relationship that we started to dig into in First Class and would like to mine more in this one."

Although details about the film are being kept under wraps, Kinberg acknowledged that the film will mark the end of an arc for the main characters in the franchise.

"This movie is the completion of the first arcs of Charles, Eric, Raven, and Hank, who are essentially our main characters," he said.

"They're such young actors and young characters, so there's a lot more story to tell. But as a first phase of their lives, there is this feeling of closure by the end of the movie."

X-Men: Apocalypse is expected to be released in May 2016.
