The cast for Deadpool 2 director David Leitch's new Bullet Train movie starring Brad Pitt continues to add to its already impressive lineup.

After Heroes star Masi Oka and Oscar-nominated actor Michael Shannon boarded the movie, Collider reports that singer/actress Lady Gaga will also have a role in the film.

The movie follows a group of assassins on a speeding train in Tokyo. Collider's source said Lady Gaga's part is a "smaller supporting role."
