11 big actors you didn't realize were in 'A Series of Unfortunate Events'

This post includes spoilers for "A Series of Unfortunate Events."

Netflix's new show, "A Series of Unfortunate Events," is based on Daniel Handler's beloved children's book series of the same name.

One of the series' greatest strengths is its cast of colorful, absurd, and creatively named characters — from Quigley Quagmire to Person Of Indeterminate Gender. You probably already know Neil Patrick Harris as Count Olaf, the scheming evil actor who tries to whisk away the fortune of the Baudelaire orphans, and Patrick Warburton as Lemony Snicket, Handler's authorial alter ego and the on-screen narrator of the series. There are also Malina Weissman, Louis Hynes, and Presley Smith who play Violet, Klaus, and Sunny Baudelaire.

The rest of the show's cast — from Justice Strauss to Dr. Montgomery Montgomery — are played by surprisingly major actors cameoing in the series. Here's a list of who they are, as well as a handful of characters who don't appear in the book.

Joan Cusack plays Justice Strauss, Count Olaf's neighbor who tries to help the children in "The Bad Beginning."

Broadway star and character actor Ken Todd Freeman plays Mr. Poe, the ineffectual banker in charge of the Baudelaire estate.

Former "Daily Show" comedian Aasif Mandvi plays Doctor Montgomery Montgomery, AKA Uncle Monty, the herpetologist who takes care of the orphans in "The Reptile Room."
