The latest round of X-Men: First Class reports that began early this morning with a rumor that Aaron Johnson has signed on to play Scott Summers and continued with news that Nicholas Hoult and Caleb Landry Jones have been cast as Henry McCoy and Sean Cassidy still has more to give: According to Hollywood Insider, Lucas Till is in negotiations to play Alex Summers, aka Havok.

If you're not up on your mutant history, Havok is the hot-headed younger brother of Scott Summers who can generate powerful plasma waves.

The Entertainment Weekly blog cautions, however, that Till and the other young actors may not actually be playing these roles: "Instead, this could be part of a misdirection campaign to keep some surprises from X-Men fans." For its part, Fox hasn't confirmed any cast members beyond James McAvoy, Michael Fassbender and, I think, Alice Eve. And Hollywood Insider asserts that Johnson won't be in the movie.

The 19-year-old Till is best known as the cowboy hat-wearing beau in Hannah Montana: The Movie. He'll next appear in Vacation 8 and Battle: Los Angeles.

If these latest reports are accurate, the cast of X-Men: First Class is shaping up to look something like this:

• James McAvoy: Charles Xavier

• Michael Fassbender: Erik Lensherr

• Aaron Johnson: Scott Summers (or not)

• Alice Eve: Emma Frost

• Nicholas Hoult: Henry McCoy

• Caleb Landry Jones: Sean Cassidy

• Lucas Till: Alex Summers

There are, of course, other casting rumors, such as Kevin Pennington as Jamie Madrox/Multiple Man, Amber Heard and Rosamund Pike as Mystique and Moira MacTaggert, and so on. There was even that odd report that surfer Erica Hosseini had auditioned to play Willow, an obscure shapeshifter from the short-lived '90s series X-Nation 2099.

Directed by Matthew Vaughn, X-Men: First Class begins production next month in London and opens on June 3, 2011.
