Sean Lennon Scoring and Acting in New Film

Lennon, who also makes a cameo as a super villain, began working on the project earlier this summer, composing what Galland describes as "an epic superhero sound."

This is the second time that Lennon has scored a film by Jordan Galland, the first of which was the critically acclaimed Rosencrantz And Guildenstern Are Undead, an indie romantic comedy about vampires, Shakespeare and the Holy Grail, released in the summer of 2010.

Alter Egos, which began production this past spring in New York City and Long Island, follows an underappreciated superhero at a time when superheroes have lost government funding and all public support.
