Obviously designed as an exploitationer, It's a Small World isn't bad within its own limits. Paul Dale, a real-life radio disc jockey, stars as midget Harry Musk, who is met with cruelty and insensitivity wherever he goes because of his small stature. Unable to adjust to the "big" world, Harry falls in with bad company and becomes a criminal. Redemption comes in the form of midget Dolly Burke (Anne Sholter), who convinces Harry to go straight and pursue an honest living as a performer with the Cole Bros. circus. The "normal-sized" cast is populated with such familiar faces as Will Geer, Steve Brodie, Todd Karns and Margaret Field. Director William Castle also shows up in a cameo role as a police officer.
