Rehab guru 'Jacked' for CMT

John Irwin producing series hosted by C. Thomas Howell

After making a name for himself in the celebrity rehabilitation genre with VH1's "Celebrity Rehab With Dr. Drew" and its spinoffs "Sober House" and the upcoming "Celebrity Rehab -- Sex Addition," reality producer John Irwin is branching out with "All Jacked Up," a hillbilly-themed series for CMT.

Slated to premiere at 8:30 p.m. Aug. 22, "All Jacked Up" features host C. Thomas Howell traveling the country in search of outlandish, funny and extreme stunts, sports, events, people and inventions.

Each of the eight half-hour episodes, from Irwin Entertainment, contains four segments featuring subjects ranging from eating contests and ostrich racing to demolition derbies, jet-powered outhouses and chainsaw jugglers.

Although he makes a good living as a reality producer ("Celebrity Rehab" is in production on its third season, and "Sober House" recently was renewed for a second season), Irwin also stays close to his comedy roots.

He recently wrapped a one-hour stand-up special starring Nick Swardson, which Comedy Central is set to air and release on DVD in the fall.

Starting off as a producer on "Late Night With Conan O'Brien," "Mad TV" and as a development and production executive at Lorne Michaels' Broadway Video, Irwin went on to produce a slew of comedy series, pilots and specials before venturing into unscripted TV.
