The first official X-Men: First Class trailer from February remains the only one for the X-Men prequel to release in North America, but last week we did get an amazing retro ’60s style X-Men: First Class opening sequence to fill the void.

While we await the next official trailer from Twentieth Century Fox, we watched the powerful and moving Russian trailer which offered more mutants and an epic score. This time around, we have the same international trailer, but made for Japan with the voices left in English, giving viewers their first real earful of Charles Xavier (James McAvoy) and Erik Lehnsherr (Michael Fassbender) hinting at their journeys to come.

There’s certainly no hiding how Magneto and Professor X came to be on opposite sides of the mutant phenomenon and arguably might be the most compelling plot point of the movie. This X-Men: First Class trailer goes to show how Charles has already taken on the role of a mentor with the mutant group they formed, attempting to convince Lehnsherr that he’s powerful and can use his abilities for good, whereas Lehnsherr is determined to establish mutantkind as the dominant species. While his violent tendencies come off as villainous, we cannot help but feel sympathetic for Magneto’s cause based on his past experiences.

Watch and enjoy:

How does that compare to Green Lantern, Captain America and Thor?

We’ve been totally fooled by X-Men trailers before, as evidenced by the final product of X-Men Origins: Wolverine, but what we’ve seen so far from director Matthew Vaughn’s First Class does make it look like the most interesting and intriguing superhero film of the summer, especially when it comes to story and characters.

This trailer alone, makes me want to see what Vaughn and Bryan Singer can do with the main X-Men team, should X-Men: First Class successfully launch a trilogy of its own.

X-Men: First Class‘ cast includes James McAvoy, Michael Fassbender, Kevin Bacon, Jennifer Lawrence, January Jones, Rose Byrne, Nicholas Hoult, Jason Flemyng, Zoë Kravitz, Lucas Till, Oliver Platt, Ray Wise, Edi Gathegi, Caleb Landry Jones and Álex González.

X-Men: First Class hits theaters June 3rd, 2011.
