Penny Marshall
Garry Marshall, creator and then part-time writer for "Happy Days", cast Marshall and Cindy Williams to guest on an episode of the show. The installment, titled "A Date with Fonzie", aired on November 11, 1975 and introduced the characters Laverne DeFazio and Shirley Feeney (played by Marshall and Williams, respectively). In that episode, Laverne and Shirley were a pair of wisecracking brewery workers who were dates for Fonzie (Henry Winkler) and Richie (Ron Howard). The pair were such a hit with the studio audience that Garry Marshall decided to co-create and star them in a successful spinoff, "Laverne & Shirley" (1976–1983). The characters of Laverne and Shirley appeared in five more episodes of "Happy Days". In 1982 at the beginning of "Laverne & Shirley"s eighth season, Williams left the show due to her pregnancy. Marshall continued with the show, but it was canceled after the season's final episode aired in May 1983.

One such project titled "Four Stars" was directed by Lynda Goodfriend (who portrayed Lori Beth in "Happy Days"), and was based on a play Goodfriend had read when she was studying at the Lee Strasberg Center, which had been written by John Schulte and Kevin Mahoney. It starred Julie Paris (the daughter of Jerry Paris) and Bert Kramer. Schulte later co-wrote with TV veteran writer and producer, Fred Fox, Jr., who penned and produced a number of Marshall's television series, including "Happy Days" and "Laverne and Shirley". Marshall went on to focus on directing feature films, with a series of hits, such as "Beaches", "Pretty Woman", "The Princess Diaries", "Valentine's Day", and "New Year's Eve".
