Based on the children's books by Dan Santat, the Disney animated series The Replacements concerned itself with a pair of orphan children, Riley and Todd, who took it upon themselves to order two "normal" foster parents from the Fleemco Replacement Parent Organization. Instead, they ended up with a mom who was a British superspy named Agent K and a dad who was a foolhardly movie stuntman named Dick Daring. And oh yes, Riley and Todd also fell heir to a Knight Rider-style talking automobile named C.A.R.T.E.R., or C.A.R. for short (its voice was wittily supplied by former "Man from U.N.C.L.E." David McCallum). Offering two fast-paced adventures per half-hour episode, The Replacements premiered September 8, 2006, on cable's Disney Channel, and not long afterward joined the weekend-morning lineup on Disney's sister network ABC. ~ Hal Erickson, Rovi
