Although she might be the newcomer on “X-Men: Apocalypse,” Sophie Turner is no novice as her acting credentials include a featured role in “Game of Thrones.” Yet it seems the actress has yet to overcome a particular weakness that could become a problem for any project she’s in.

The 20-year-old actress revealed her difficulty to “keep plot points a secret,” Metro reported. Turner, along with co-star Evan Peters, spoke with Cassam Looch from the publication as part of the promotions for “X-Men: Apocalypse.”

“Its difficult for me in like every situation just because I get so excited and I just want to tell everyone,” Turner revealed. However, Turner wasn’t shy to reveal the one superpower she wanted. Looch asked both actors about Jennifer Lawrence’s role as a teacher to their characters Quicksilver and Jean Grey. In response, Turner stated Lawrence and the other cast members were technically 40 in “X-Men: Apocalypse,” hence, her motherly quality.

“Yeah, because First Class was 63, and then Days of Future Past 73 … it’s a mutant thing” Turner explained. “She goes back to her younger self. That would be a good superpower to have if you’re an old lady,” Peters replied to indicate his agreement. “That’s right! That’s the one I want,” Turner said.

The GoT actress is certainly excited about her role in “X-Men: Apocalypse.” She revealed how much she identified with both her characters, Sansa Stark and Jean Grey. “Both Jean and Sansa are strong characters with such great arcs. Neither starts out strong, but they find that power within them, whether literally or metaphorically,” she told Self Magazine. Sophie Turner is the cover star of the June 2016 issue of SELF.

Sophie Turner takes over the role of Jean Grey from actress Famke Jannsen. CNET wrote that she stood out among the new generation of actors who took over the principal X-Men characters. Indeed, her first photo as the young Grey alongside a young Cyclops (played by Tye Sheridan) helped raise anticipation for the movie.
