You may remember Mackenzie Astin from his younger days, when he was hanging out with
Blair, Tootie, Natalie, and Jo at Edna’s Edibles and Over Our Heads on The Facts of Life, but he's been out of Peekskill for quite some time now. Only last year he could be found squaring off against Jon Hamm during one of the final episodes of Mad Men, and that's far from the only high-profile gig he’s had lately: over the past few years, he’s turned up on Grey’s Anatomy, NCIS, Criminal Minds, Shameless, Bones, Agents of S.H.I.E.L.D., Scorpion, and Castle, among others, and he had a recurring role on Scandal last season that carried over into this season as well. When we talked to him for the debut episode of Obscurity Knocks, he couldn't talk about his latest endeavor, joking that "the nondisclosure agreement I just signed had its own nondisclosure agreement," so just keep your eyes open for him. But that's good advice in general: as you can see from the above list of credits, you never know where that guy is going to show up next!
