Celeb Cast Reunions

Seeing your favorite costars – When Harry Met Sally! Mary Poppins! Friday Night Lights! – get back together after years apart is true Hollywood magic

JONATHAN & ZACHERY

Girls of the '90s likely melted a bit seeing JTT and Zach – Home Improvement's Jonathan Taylor Thomas and Zachery Ty Bryan, that is – back together at a Los Angeles movie premiere on Aug. 14. Don't hold your breath for a series reunion, though; asked about fame earlier this year, Thomas told PEOPLE, "It was a great period in my life, but it doesn't define me."
