Director may not be a huge fan of Easter eggs, but and Fox definitely realize that one of the main draws for seeing The Wolverine is the possibility of nods or footage of 's upcoming X-Men: Days Of Future Past.
Speaking with CNN, Jackman said that there will be an after-credits that showcases a tiny bit of Singer's film. I'm assuming that Singer and co. will be revealing this footage on July 20 during their Comic-Con panel. There were rumors that and Jackman shot a scene together to set up DoFP, but from this clip, it seems that it's going to actually be a teaser for the new film.
The Wolverine opens July 26.
