Re: The marketing for this film...
Yeah they should have had a teaser trailer in December, but times have changed just like how Blu-rays/DVDs of theatrical films come out earlier.
Its not only The Wolverine that released a trailer 4 to 5 months before the release date. The Hangover Part III is coming out before The Wolverine and I don't think there's a trailer for that movie yet.
X-MEN: DAYS OF FUTURE PAST
The future of X-Men's original trilogy cast begins this May!
Hugh Jackman - Halle Berry - Ian McKellen - Patrick Stewart
