William Winckler is an American actor, businessman, director, producer, and independent filmmaker best known for writing, producing and directing cult movies, horror films and English dubbed animation. He is the son of child actor Robert Winckler.

Billy Barty was an American actor and activist. In adult life, he stood 3 ft 9 in (1.14 m) tall, due to cartilage–hair hypoplasia dwarfism. Because of his short stature, he was often cast in films opposite taller performers for comic effect. He specialized in outspoken or wisecracking characters. During the 1950s, he became a television actor, appearing regularly in the Spike Jones ensemble. In the early 1970s he was a staple in a variety of roles in children's TV programs produced by Sid and Marty Krofft. Also an activist for people with dwarfism, he founded the Little People of America organization in 1957.
