Before we start, I'll like to say that as I put this cast together I had in mind the idea of puting together a relatively young group. The Organizer and overseer of the group is Valerie Cooper, While the leader is Havok. Jamie Madrox would be the main character and rival of Havok, who only views Jamie as an criminal.
Valerie Cooper - Serinda Swan
Serinda Swan has played Zatanna in Smallville and Erica Reed in Breakout Kings. Shes a good Actress and would do well in this part as an authoritive figure.
After witnessing first-hand the deeds of mutants throughout the years, Valerie Cooper wanted to give the concept of a government sponsored team another shot. She was able to convince several members of the X-Men and their associates to form a new X-Factor team, acting as an government liaison to the team.
Havok - Garrett Hedlund
The leader of the government-sponsored X-Factor. He's a strong leader, with a tight grip on his team. He doesn't think much of Madrox, and even thinks of it as an insult to have Madrox on his team.
Garrett has a definite look that jives well with this version of Havok. He also did well in Tron, which lead me to choosing him for this role.
Multiple Man - Hayden Christensen
Jamie madrox is an mutant bank robber who after being caught, is brought before Valerie Cooper, after she put an request in for another strong mutant. He accepts an spot on the team, and immediately emerges as an potenial leader, to the dismay of Havok. One of the underlying themes in the movie would be if Madrox is actually a mutant, or something much more greater.
Hayden Christensen is best know for his role as Anakin Skywalker in the Starwars Prequels, which lead me to choosing him. He has the dynamic needed in order to sucessfuly play Madrox.
Strong Guy - Domenico "Domenick" Lombardozzin
Strong Guy is an Italian American Mutant.
Lombardozzin is best known for his role in breakout kings.
Polaris - Keira Christina Knightley
Hayden Christensen is best know for his role as Anakin Skywalker in the Starwars Prequels, which lead me to choosing him. He has the dynamic needed in order to sucessfuly play Madrox.
