Via the X-Men: First Class Facebook page, we get a new shot of Lucas Till as Havok and it's on fire. It's a departure from what I remember the character looking like in the comics but this could be an early shot before he dons any sort of official "X-Men" attire.
The jury is still out on this one. The posters released so far have just been bland and disappointing. The "Before he was...he was..." slogan is already tiresome since it's been thrown in every bit of promotional material so far it seems. There's still a lot to see here and I'll hold off on a final judgement until the film is released.
X-Men: First Class will be released June 3rd later this year.
