Tim Robbins will reportedly be joining the cast of "Iron Man 2." The "Shawshank Redemption" star is set to play Tony Stark's father in the sequel to the blockbuster film.

According to Latino Review, the 50-year-old actor will star as Howard Stark in an important flashback sequence in the upcoming film. If the report is true, then he will be replacing Gerard Sanders for the role. Sanders played Howard in a montage scene in the first film.

Although still not confirmed, screenwriter Mark Fergus had revealed in September that the sequel's storyline would include Tony/Iron Man's relationship with his father.

It was also reported in October that Terrence Howard, who played James Rhodes, will not be coming back in the second film. Don Cheadle will be replacing him for unknown reasons.

"Iron Man 2" is slated for a 2010 release.
