'Home Improvement' Reunion: Richard Karn To Visit 'Last Man Standing' And More Casting News

It's Tool Time on "Last Man Standing." Tim Allen's former "Home Improvement" co-star, Richard Karn, is set to appear in an episode of Allen's ABC comedy in the new year, TV Line reports.

Karn will play Bill, "a gruff good old boy and the Outdoor Man’s original architect. He is dumbfounded when he learns he may be losing the account to a young, gorgeous woman — who he assumes got the job because of her good looks."

It's not the only positive news "Last Man Standing" received this week -- ABC also commissioned five additional episodes of the series (and its Friday night companion "Malibu Country"), for a total order of 18 this season.
