Howard, 64, remembered Marshall, who died of complications from diabetes, as “funny” and “smart” in a tweet he shared on Tuesday. “#RIPPennyMarshall She was funny & so smart. She made the transition from sitcom star to A List movie director with ease & had a major impact on both mediums,” the Solo: A Star Wars Story director wrote. “All that & always relaxed, funny & totally unpretentious. I was lucky to have known & worked with her.” Howard starred as Richie Cunningham in the family show opposite Winkler, 73, who portrayed Arthur “Fonzie” Fonzarelli, the local bad boy. Marshall played Laverne DeFazio, a tough-talking tomboy.

In a statement to PEOPLE, Winkler said, “I first met Penny one month after having arrived here in LA. I was a guest star on a TV pilot she was working on.” Tom Hanks, Geena Davis and the Cast of A League of Their Own Remember Director Penny Marshall “The next time we worked together was on that iconic episode of “Happy Days.” She was so inventive, so funny and so warm,” he continued. “She brought her own unique brand of humor to what was on the written page. Watching her playing Laverne, I remember thinking, ‘Wow,” she has just created the 20th Century Lucille Ball.”” ABC via Getty Rob Reiner Remembers Ex-Wife Penny Marshall After Her Death at 75: ‘So Sad’ Other Happy Days cast members such as Anson Williams, who played one of Richie’s best friends Potsie, remembered the Big director, telling Deadline in a statement, “Penny was as courageous as she was talented, and broke down the wall for women directors.
