Congratulations NBC on your renewal of Chuck--March is a long time to wait for the fans,but the quality of the show makes the wait well worth it. The primary strength of the show is the quality cast. I really think it would be a smart move to sign the primary cast members for a fouth full season as soon as possible. Several of the cast members will be catered to by other networks, I am sure you are aware of which cast members will be in high demand. I understand the show "Bones" on another network signed their main people for two years. Chuck is every bit as good (I consider it better) than Bones.
