Director tweets Wolverine spoiler
The Wolverine director James Mangold has posted a teaser clip of the film online, revealing a surprise cameo.
During the action-packed six-second clip of the upcoming spin-off movie starring Hugh Jackman as the X-Men mutant, Famke Janssen appears briefly on screen.
This confirms the long-running rumour that her X-Men character Jean Grey - who died in X-Men: The Last Stand - does appear in the new film. It could be a flashback scene, since her character is dead.
Mangold has given nothing further away, simply announcing the clip which is packed with fight scenes from Jackman, as a "tweaser".
The full trailer is released later this week and the film is out in July.
The Wolverine follows Jackman as Logan, trying to battle his past demons while getting into new problems in Japan.
