Jennifer Lawrence wasn’t a household name when “X-Men: First Class” hit theaters in 2011. Three years later, she has an Oscar on her mantel thanks to “Silver Linings Playbook,” and a monster franchise in her quiver with the global success of “The Hunger Games.”

Lawrence’s rising star is paying off for the latest “X-Men” adventure. Nearly three-quarters of ticket buyers said that they were motivated to see “X-Men: Days of Future Past” because of her role as the shape-shifting Mystique, according to a survey by online ticketer Fandango.

“X-Men: Days of Future Past” opened in theaters on Thursday night and is expected to dominate the Memorial Day box office. Fandango reports that it is responsible for more than 90% of its weekend pre-sales.

The Fandango study is unscientific and the sample size of 1,000 participants is small, but it does show that the decision to have Lawrence’s character factor into the plot more centrally this time round was a wise one. Mystique is front-and-center in the film’s posters and marketing materials and the fate of mutant-kind rests in her scaly blue hands.

Among other findings, 88% of those surveyed said they have seen the previous “X-Men” movies on the big screen and 82% are looking forward to the next film in the franchise, “X-Men: Apocalypse.” That film lands in theaters in 2016, but “Days of Future Past” has a post-credits teaser that may give fans a glimpse of what they can expect from the follow-up.
