Sophie Turner feared her new
film would be the worst movie in the franchise because of her part in it.
The super mutants have reunited for X-Men: Apocalypse, bringing back together A-listers like Jennifer Lawrence, James McAvoy and Michael Fassbender.
There are plenty of new names thrown into the mix too, including Sophie, Olivia Munn and Oscar Isaac.
While the casting was an exciting one,
star Sophie was unsure how successful
"This is going to be the worst X-Men so far, because I'm in it," she admitted to Britain's InStyle magazine of her doubts.
"When you're outside something, you think, 'That is amazing, I would love to be in that.' But when you are in it, you think, 'Is this going to be any good?"
Sophie is one of a number of stars who got their big break on the hit fantasy drama Game of Thrones, based on the novels by George R. R. Martin, which is currently in its sixth series.
While the cast are vague about how many seasons there will be, Sophie is adamant it won't go past eight. That means the end is near for the stars - a thought that scares 20-year-old Sophie.
"I kind of had a bit of a panic attack the other night as I was thinking about it. It's like graduating from high school, but it doesn't feel like a graduation, because I don't have a university to go onto that's bigger and better," she explained.
X-Men: Apocalypse is in theatres now, and has won favourable reviews from critics and cinemagoers.
