Alex Wolff, who you may remember from your Nickelodeon throwback fave, Naked Brothers Band, is starring in a new movie — and his role is major. The actor is playing Dzhokhar Tsarnaev, who was the younger of the Boston Marathon Bombers.

It's a pretty crazy casting decision, and marks a departure into more serious roles for the actor. Alex will be starring alongside Themo Melikidze, who is playing his older brother in the movie.
