It was the largest gathering of little people ever, drawn from all over to appear in the movie of a classic children's story. They weren't in Kansas anymore. They were in Hollywood, home of wide-open lifestyles and nonstop parties. This colorful screwball comedy uses the premise of 150 little people playing The Wizard of Oz's Munchkins housed in one Culver City hotel - and indulging in some high-energy partying - to spin zany screen mayhem with touches of romance (between G-man Chevy Chase and casting maven Carrie Fisher) and cockeyed espionage (involving German agent Billy Barty and Japanese spy Mako). Co-stars Eve Arden, Adam Arkin, Joseph Maher and Pat McCormick deliver tall orders of laughter, while smashing into small-fry shenanigans at every turn. There's no place the Rainbow.
