Watch : Home Improvement’s Jonathan Taylor Thomas Seen in Rare Reunion PhotoJonathan Taylor Thomas’ latest sighting would be hard to improve on. The Home Improvement star, who stepped back from Hollywood in 2015, made an extremely rare appearance reuniting with former costars Patricia Richardson and Taran Noah Smith. Richardson, who played mom Jill Taylor, shared a glimpse into the sweet reunion with Thomas, who played Randy, and Smith, who played Mark. The 44-year-old’s once famously dirty blonde appears to be a darker brown as he squeezed in alongside Richardson and Smith. Thomas’ rare outing comes just over a month after Tim Allen—who played Tim Taylor on the beloved 1990s sitcom—shared an update on why the cast has never reunited for an on-screen special.
