Call of Duty: Finest Hour will include work by many Hollywood big-names, including Michael Schiffer and Dennis Haysbert.

Spark Unlimited has signed some big names for their new game Call of Duty: Finest Hour. As well as actor Dennis Haysbert ("24") they have signed Michael Schiffer ("Crimson Tide") to provide the script and Michael Giacchino ("Lost") to provide the score.

"Working with Dennis, Brian, Michael Schiffer and Michael Giacchino has been a truly inspired collaboration. Each brought his own valued expertise to the project, contributing in such differing ways to the depth of realism and emotion of Finest Hour's non-stop, gripping action," said Scott Langteau, producer and COO, of developer Spark Unlimited.
