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 like …Under the Rainbow.
