Certifiably Jonathan is the first and only film to feature the appearances of all the Arquettes: Patricia, Rosanna, David, Alexis and Richmond. All the siblings, with the assistance of a medium, conduct a séance with Jonathan Winters to help summon Jonathan’s sense of humor from beyond.Jonathan is practically a family member to the Arquettes. He and their grandfather, Cliff Arquette were great friends. Both Jonathan and Cliff appeared on the Tonight Show with Jack Paar many times and sometimes together. Jonathan, of course, would appear in one of his many wacky characters, but Cliff was famous for his popular and lovable Charley Weaver character, who would usually read a letter from “Mamma” back home. Charley Weaver was also a regular on Hollywood Squares for a while.
Jonathan was good friends with Cliff’s son, Lewis Arquette, as well. Lewis, the Arquettes’ father, was also an actor. He appeared on The Jonathan Winters Show in the late 1960’s, as well as in several films and other TV shows.
Imagine growing up and having Jonathan Winters visiting your house often. How much fun that must have been for all the Arquettes. So, when they heard Jonathan had lost his sense of humor, they were more than happy to try and help him get it back.
