Every ‘Home Improvement’ Alum Tim Allen Reunited With on 'Shifting Gears'

Tim Allen‘s hit ABC sitcom Shifting Gears has allowed him to bring in numerous former cast members from Home Improvement.

Before playing a widower on Shifting Gears, Allen got his sitcom start on the latter show, which ran from 1991 to 1999 and also starred Jonathan Taylor Thomas, Patricia Richardson, Taran Noah Smith, Zachery Ty Bryan, Richard Karn and Debbe Dunning.

Allen continued to find success playing Mike Baxter in Last Man Standing from 2011 to 2021 before returning to TV alongside onscreen daughter Kat Dennings. While speaking exclusively to Us Weekly in January 2025, Allen weighed in on the possibility of reuniting with his former costars.

“Everything is a possibility,” he shared before addressing a possible appearance from Thomas after he took a step back from the spotlight. “He just came back [to the last episode we filmed]. He showed up on the set.”

Allen said he would love nothing more than to share the screen with Thomas again. “He’s literally my kid. I raised that kid for eight years on Home Improvement,” he added. “All of these are my kids, and I’m kind of sick about this.”

At the time, Allen recalled the close bonds he formed with his onscreen kids throughout the years.

“[My former onscreen wife] Nancy Travis once told me [something] after I called her during Last Man Standing. I said, ‘Have you talked to the girls [who play our daughters] over the summer?’ Then there’s this long pause and she goes, ‘Tim, these aren’t our daughters and I’m not actually your wife,'” he quipped. “She was so wonderful about it because sometimes when they were having trouble on the show, I’d go, ‘How do you think they feel?’ And she would respond, ‘Tim, they’re actors. We just read [what is on the page but] she’s not really that sad.'”
