Last month saw several new faces join Zac Efron in the Ted Bundy-centred Extremely Wicked, Shockingly Evil and Vile, and now Jim Parsons has been added to the picture.

Parsons, of course, is best known for his turn as uber-nerd Sheldon in The Big Bang Theory, and The Hollywood Reporter brings word that he’ll be playing Larry Simpson in the film. Simpson was the lead prosecutor of the 1979 trial that finally saw Bundy convicted. As well as Efron, the movie also has Lily Collins, Grace Victoria Cox, Jeffrey Donovan and John Malkovich signed up.

The early word on Extremely Wicked, Shockingly Evil and Vile has the effort pegged as “telling the story of the infamous serial killer, focusing on how a man’s routine traffic stop spirals out of control when he’s brought up on criminal charges, a process that reveals his vast crimes.”

To be directed by Book of Shadows: Blair Witch 2’s Joe Berlinger, Extremely Wicked, Shockingly Evil and Vile has yet to be given a set release date.
