There are many questions surrounding the Poltergeist reboot in the works through MGM, Fox and producer Sam Raimi. One of the big ones: How do you possibly recast Zelda Rubenstein as heroic medium Tangina Barrons?

It looks like the answer is, "You don't." Instead, the makers of Poltergeist have cast Mad Men and Sherlock Holmes: Game of Shadows actor Jared Harris in a lead role, one that sounds similar to the part that Rubenstein played.

Deadline reports Harris will play "Carrigan, a larger-than-life TV personality who left the world of academia behind to become the star of basic cable TV show Haunted House Cleaners." Sounds like he's exactly the guy to rescue a poor little child from the clutches of a haunted television set, no?

Harris joins a growing cast that includes Sam Rockwell and Rosemarie DeWitt. Gil Kenan is directing Poltergeist based on a script by David Lindsay-Abaire.
