Though her X-MEN character Jean Grey was killed off to save her
fellow mutants in the last film, Famke Janssen has signed a deal to
return for 20th Century Fox and Marvel Entertainment's X-MEN 3, to be
directed by Matthew Vaughn.

As expected, Hugh Jackman has made a deal to return as Wolverine,
and Halle Berry, Ian McKellan and Patrick Stewart are moving the
same way for a film to shoot this Summer. A release date of May 26,
2006, is planned.

The demise of Janssen's psychic character in the last go-around will
not be ignored, as she will this time evolve into a character called
'Phoenix'.
