Lowell Ganz

Lowell Ganz is an American screenwriter, television writer, and television producer. He is the long-time writing partner of Babaloo Mandel.

Ganz grew up in Queens, New York. He dropped out of college and moved to Los Angeles, California to pursue a career writing for sitcoms, starting with The Odd Couple. From there, he moved on to writing for the TV series Happy Days and created two of its spin-off series, Laverne and Shirley and Joanie Loves Chachi.

In 1982, Ganz and Mandel teamed up with Happy Days actors Ron Howard - who wanted to start directing - and Henry Winkler - who wanted to move away from his image as the Fonz - to make their first film, a low-budget comedy called Night Shift, which was also actor Michael Keaton's first film. Ganz's second film outing, Splash, made stars of Tom Hanks and Daryl Hannah and earned him an Academy Award nomination for Best Original Screenplay.

Ganz and Mandel went on to write several other films, four more of which were also directed by Howard, and one of which had Penny Marshall, who starred in Laverne and Shirley, as director. Four of their films have featured Billy Crystal, two have featured Tom Hanks, and two are about baseball. Ganz and Mandel are also widely used as Hollywood script doctors, known for their reliability and fast turnaround time.
