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.
Me. I Am Psylockolussus... The Elusive Mutant.
