In the wake of successful stunt series Jackass, which aired on MTV from 2000 to 2002 and spawned two theatrical movies, the network is launching two new extreme reality stunt series, Dudesons in America and MTV’s Parkour Challenge, according to the Hollywood Reporter. Dudesons features four Finnish stuntmen who will perform stunts and pranks, with Jackass mastermind Johnny Knoxville executive producing. (The group was featured in a Spike TV series back in 2006, as well.) Parkour Challenge aired as a one-hour special in October and is described as a “foot race through a cluttered urban environment where racers scale obstacles.,” a la the opening action sequence of Casino Royale.
