The Playlist recently chatted with actor Tim Blake Nelson, who revealed that he is still signed onto future installments of the Hulk franchise, where he will reprise his role as Samuel Sterns from the 2008 movie The Incredible Hulk, if asked to do so.
"I am, but it's a question as to whether they'll make more movies, which was the [original] intention, or whether they'll take a fresh start with the villains, since they switched Bruce Banner to Mark Ruffalo. I certainly very much want to return as the Leader and I hope they'll have me. The intention was that I would come back, which is why my head starts to, um, bubble, at the end. It's just a question as to whether a) they're going to make more Hulk movies, and b) because of Ruffalo, if they're going to use me again."
In the comic books, Samuel Sterns transforms into the Leader after being exposed to the same gamma radiation that turned Bruce Banner into The Incredible Hulk. With The Avengers still a few years off, it will be interesting to see how the The Incredible Hulk saga plays out.
