Bill Walsh, American screenwriter and producer (d. 1975)
William Crozier Walsh (September 30, 1913 – January 27, 1975) was a film producer, screenwriter and comics writer who primarily worked on live-action films for Walt Disney Productions. He was born in New York City. For his work on Mary Poppins, he shared Academy Award nominations for Best Picture with Walt Disney, and for Best Writing, Screenplay Based on Material from Another Medium with Don DaGradi. He also wrote the Mickey Mouse comic strip for more than two decades. He died in Los Angeles and was interred in Glendale's Forest Lawn Memorial Park Cemetery.

In 1970 an article in Variety listed him as the second most successful film producer of all time in terms of money-earning movies even though he was "a guy no one's ever heard of".
