Jason Alexander, best known for his role as George Costanza on “Seinfeld,” played the terrifying unsub Professor Rothchild in this particular “Criminal Minds” episode, and was met with praise, the episode holding an enviable 8.4/10 user rating on IMDb. The episode is particular memorable, too, due to the long, white-haired wig Alexander wore on the episode, a stark departure from the bald-headed George.
Though “Seinfeld” may be Alexander’s biggest role, the talented actor has appeared in many other projects since the world-changing sitcom concluded in 1998. These include quirky crime procedural “Monk,” coming-of-age comedy “Everybody Hates Chris,” and as a fictionalized version of himself in multiple episodes of “Curb Your Enthusiasm.” Most recently, Alexander has lended his voice acting talents to the role of Sy Bergman in the Harley Quinn animated series, as well as an arc on popular “Big Bang Theory” spin-off “Young Sheldon.”
We’ll never get tired of spotting some of our favorite actors as guest stars during our many “Criminal Minds” rewatches, and Jason Alexander’s episode will always stand out as one of our favorites.
