New "The Wolverine" teaser clips reveal major "X-Men" cameo Hugh Jackman has his claws sharpened and raring to go in two newly-released promo spots for the upcoming "X-Men" "sidequel," "The Wolverine." On Monday, the film's director, James Mangold, posted a six-second teaser to the teaser trailer (you read that right) on his Twitter account: That 6-second clip revealed the possibility of a return of Famke Janssen as Jean Grey. Her character died in "X2" before being resurrected as Phoenix in 2006's "X-Men: The Last Stand," which marked her last appearance in the film series...until now. On Tuesday, we got to see even more of "The Wolverine" with the official release of the 20-second teaser trailer. While the clip is short in length, there are plenty of clues and images to keep fans guessing about what to expect when the film opens on July 26: "What they did to me...What I am...Can't be undone," Logan a.k.a. Wolverine declares in the new spot. "Don't be so sure," a mysterious figure warns him. In the new teaser we also get to see a bit of Yukio, a female ninja from the comics with connections to Wolverine's past, making her big screen debut. A follow-up to 2009's "X-Men Origins: Wolverine," "The Wolverine" is set in Japan following the events of the original "X-Men" trilogy. Wolverine will continue to learn more about his past as he puts his mutant powers to good use. The character was last seen in a memorable cameo in 2011's "X-Men First Class." Aside from "The Wolverine," Jackman will also reprise the role in 2014's "X-Men: Days of Future Past," a mash-up starring actors from the prequels as well as the original "X-Men" trilogy of films. And we'll soon get to see even more of "The Wolverine" as a full-length 2-minute trailer is expected to debut on Wednesday. Tell us: What do you think of the teaser clips?
