Tim Blake Nelson to be Samuel Sterns (a.k.a. The Leader) Tim Blake Nelson has joined the cast of Marvel Studios' The Incredible Hulk, says The Hollywood Reporter. The movie, which Louis Leterrier is directing, sees Bruce Banner/Hulk on the run, trying to avoid capture long enough to cure the condition that turns him into a monster. Nelson will play a scientist named Samuel Sterns. In Hulk lore, Sterns, aka "The Leader," is one of the Hulk's major antagonists, a menial worker in a chemical research plant who is bombarded with gamma radiation. He emerges from his accident not only green-skinned but also superintelligent, with an oversized brain. Nelson joins a strong comic book movie cast that includes two-time Oscar nominee Edward Norton (Banner), Liv Tyler (Betty Ross), Tim Roth (villain Emil Blonsky/the Abomination) and William Hurt (General Ross, Betty's father). Zak Penn wrote the latest big-screen adventure of the green goliath, which Universal Pictures is distributing domestically June 13, 2008.
