According to XMF Ilan Eshkeri is in final talks to compose X-Men: First Class for Mattew Vaughn and 20th Century Fox. Eshkeri has worked with Vaughn before on Kick-Ass, Layer Cake and Stardust, so this news was expected. Eshkeri has also composed the scores for Ninja Assassin, Hannibal Rising and The Young Victoria, so he has range when it comes to crafting music.
Each of the X-Men films has had a different composer which has resulted in the X-Men not really having a theme or continuity with the music. Spider-Man had the ‘swinging theme’. Batman has Hans Zimmer and James Newton Howard doing their thing, so I think its about time the X-Men got a theme.
