Jean Grey appeared in numerous X-Men movies from Fox's X-Men universe. First introduced in 2000's X-Men, Jean's power soared to greater heights in X-Men: The Last Stand, a controversial adaptation ...

Fox seemed to only ever want to adapt Marvel Comics' Dark Phoenix Saga to put Jean Grey front-and-center, but these adaptations (2006's X-Men: The Last Stand and 2019's Dark Phoenix) were not good.

X -Men: Dark Phoenix is the 12th and final instalment in the popular superhero franchise and tells the story of Jean Grey’s transformation from a gifted mutant into a force to be reckoned with.
