Famke Janssen has expressed that she believes Marvel made a mistake by not including her character, Jean Grey, in the upcoming Avengers: Doomsday. It appears that Janssen was not asked to return for the film, which some outlets suggest may be part of a larger X-Men reunion. However, there is some uncertainty about the extent of X-Men involvement in the movie, with one report suggesting that more classic X-Men characters may still appear.
