CBS gives MacGuyver a series order in their commitment to the show but with that comes some changes. The main premise stays the same following a 20-something MacGyver as he creates a clandestine organization where he uses his knack for solving problems in unconventional ways to help prevent disasters from happening. Paul Downs Colaizzo and Brett Mahoney brought in to help the pilot are now exiting the project with Hawaii Five-0 executive producer showrunner Peter Lenkov tasked with writing a new script. The host of characters around MacGyver is expected to change as, besides co-star Eads, the entire supporting cast is gone. The pilot originally had seven regular roles, with Addison Timlin, Joshua Boone, Michelle Krusiec among those departing.
