Writers for Spider-Man: Brand New Day have indicated that Jean Grey does not kill anyone in the film. The clarification matters because it avoids linking the character to violent acts before Marvel Studios’ planned X-Men film introduces its own version of the mutant team.

The report treats the detail as a reassuring sign for continuity between Marvel projects, particularly given Jean Grey’s significant and often destructive comic-book history. It also reflects continued uncertainty over how X-Men characters may be introduced into the wider Marvel Cinematic Universe.
