 Sid Sheinberg (qv), the head of Universal Pictures, requested many  changes to be made throughout the movie. Most of these he got, such  as having "Professor Brown" changed to "Doc Brown" and his chimp  Shemp changed to a dog named Einstein. Martys mothers name had  previously been Meg and then Eileen, but Sid Sheinberg (qv)  insisted that she be named Lorraine after his wife  Lorraine Gary (qv).
