Amazon PrimeIn Highston, Highston Liggetts (newcomer Lewis Pullman) is a 19-year-old with a wide circle of celebrity friends—that only he can see. His parents, Jean (Mary Lynn Rajskub, 24), and Wilbur (Chris Parnell, Saturday Night Live) force him to get psychiatric help, but his Uncle Billy (Curtis Armstrong, American Dad!) thinks he’s just fine. Highston is a comedy about what it means to be normal in a world that’s anything but. The pilot guest stars Shaquille O’Neal (Thunderstruck) and Flea (The Big Lebowski), and is written by Bob Nelson, directed by Independent Spirit Award winners Jonathan Dayton and Valerie Faris, and executive produced by Sacha Baron Cohen (The Dictator), Todd Hoffman (Love Stinks), Nelson, and Todd Schulman (Bruno).
