It's hard to believe THE GODFATHER filmmaker Francis Ford Coppola was also responsible for this charming, whimsical musical. Fred Astaire stars in his last full-length musical role as Finian McLonergan. In Ireland, Finian manages to steal a pot of gold from unlucky leprechaun Og (Tommy Steele). Finian and daughter Sharon (Petula Clark) journey to Rainbow Valley in America and join the townspeople there in defending themselves against the racist Senator Billboard Rawkins (Keenan Wynn). The buried gold becomes the lucky crock that helps Og, Finian, and the townspeople fulfill their dreams.
