Two days ago we posted the UK version of the international X-Men: First Class trailer. It was almost identical to the Japanese, Russian and French trailers aside from different subtitles, but each has slowly revealed a few mere seconds of different footage.

Another version the X-Men: First Class trailer has launched on the official Marvel YouTube channel and at first glance, it’s exactly what we’ve seen before, with a few seconds actually taken out. But if you look closely, there is literally less than one second of something we’ve not seen before, something potentially very strange related to Kevin Bacon’s Sebastian Shaw…

The one subject that the X-Men: First Class marketing hasn’t delved into at all is that of the Hellfire Club, which may end up being the most important plot point in the film. Two of the film’s leads, Emma Frost (January Jones) and Shaw (Bacon), are involved with the Hellfire Club but the trailers thus far, have focused on the Magneto-Xavier relationship and not the villainous side of things.

Let’s start with a little history about the Shaw character. Shaw is one of the greatest supervillains of the X-Men universe. He’s a natural born leader, a genius and a mutant with the powers to absorb kinetic energy, allowing him to take a severe beating, just to turn into strength against his opponents. He studied engineering, started his own company and became a billionaire before turning 40. After being initiated into the Hellfire Club, it didn’t take him long at all to become its leader and start his plans for world domination… at least that’s the way it was in the Marvel Comics.

Watch this trailer and see if you spot anything unusual:

Missed it? Check out this split-second sequence that shows up after Banshee takes flight – this is the one difference in this trailer compared to the previous ones:

One, two, three… four arms?

Now, this is either some clever tie-in marketing to this week’s release of Mortal Kombat video game (see: Goro) and the second episode of Mortal Kombat: Legacy (it’s not) or Shaw may be quite a bit different in Bryan Singer and Matthew Vaughn’s 1960s take on the mighty mutants.

Perhaps Singer, for his story, wanted to go with a villainous mutant with a more exciting power than just something physical, something with a little more flare to boost the visual side of any action sequences. Perhaps it’s just something related to that vial/hand grenade Shaw is holding onto or perhaps it’s just strange special effects animation and this trailer is intentionally throwing us all off. That’s a lot of perhaps.

What do you think is going on here?
