Time to speculate!
X-MEN: DAYS OF FUTURE PAST director, Bryan Singer recently started following “Buffy” and “Gossip Girl” actress, Michelle Trachtenberg on Twitter. Trachtenberg returned the favor, following him as well. On April 11th, she tweeted her fans about getting a new red hair color; she didn’t give the reason for the change.
This could be a random coincidence, but fans are wondering if Trachtenberg’s dye-job is connected to her being involved with Singer’s film. Likely character choices would include a young Jean Grey in the 70′s or Rachel Summers, Cyclops and Jean’s daughter from an alternate future timeline, who appears in the original DOFP comic.
