Sadie Sink to play Jean Grey in MCU's X-Men introduction

The Marvel Cinematic Universe (MCU) is set to introduce mutants following the casting of Sadie Sink as Jean Grey in ‘Spider-Man: Brand New Day’. This marks the official arrival of the X-Men franchise within the MCU.

While the film establishes Jean Grey as a high-profile mutant, it does not yet feature other core members like Cyclops or Wolverine. Reports suggest Kit Connor may play Scott Summers/Cyclops and Samara Weaving may portray Emma Frost, though other names remain subject to rumor.

Industry speculation suggests that Marvel may benefit from delaying the introduction of a new Wolverine to a sequel to maximize impact, especially as the franchise transitions into a ‘Mutant Era’ following the anticipated conclusion of Hugh Jackman’s tenure in upcoming Avengers films.
