One of Marvel Studios' upcoming movies has lost an A-list cast member – Steven Yeun has dropped out of Thunderbolts, according to The Hollywood Reporter.
Yeun's casting was first reported last February, but his involvement in the movie was never officially confirmed by Marvel. Later in the year, Invincible creator Robert Kirkman let slip that Yeun would be playing the Sentry, an all-powerful hero haunted by a dark side known as the Void.
