Fred Astaire's final movie musical...
“Finian’s Rainbow” is the first major film directed by Francis Ford Coppola (“The Godfather”). Based on the 1947 Broadway musical, this 1968 picture stars Fred Astaire and Petula Clark. Finian McLonergan (Astaire), who’s stolen a pot of gold from a leprechaun, moves to the United States with his daughter Sharon (Clark) to the mythical town of Rainbow Valley. Finian believes that if he buries the gold in the ground, it will grow like a plant and multiply. The two are soon pursued by Og the leprechaun (Tommy Steele), who wants to take back the gold from Finian.<br /><br />The movie is much too long and appears terribly quaint nowadays. The presence of Fred Astaire, in his last screen musical, makes the film worth watching, as well as a beautiful score by Burton Lane and E.Y. Harburg, which includes “Old Devil Moon,” “How Are Things In Glocca Morra,” “If This Isn’t Love,” “Look to the Rainbow,” “When I’m Not Near the Girl I Love,” “When the Idle Poor Become the Idle Rich,” and “Necessity.”<br /><br />Other characters include a bigoted Southern senator (Keenan Wynn), transformed into a black man by misbegotten magic, Susan the Silent (Barbara Hancok), a mute who communicates through dance, and Woody Mahoney (Don Francks), who has returned to Rainbow Valley to repay back taxes before his land is seized and falls for the lovely Sharon.<br /><br />Petula Clark was at the height of her popularity and does a credible job as Sharon, her songs a highlight of the film. On the other hand, Tommy Steele as Og is overbearing, giving a hammy performance. His gestures are exaggeratingly broad, his goofy smile irritating, and his acting completely lacking in subtlety. The movie is a mix of obvious studio sets and actual locations which give the production a patched-together look.<br /><br />Bonus extras on the widescreen Blu-ray release include Francis Ford Coppola’s introduction and director commentary, and  the featurette, “The World Premiere of Finian’s Rainbow.”

Here is a brief synopsis of the title : He wears a ratty old cardigan instead of tails, a battered felt hat in place of a topper – but one glimpse of those agile feet and you know he’s Fred Astaire. The great entertainer sang and danced his last musical lead in Finian’s Rainbow, director Francis Ford Coppola’s exuberant movie of the 1947 Broadway hit. Astaire plays an Irish rogue who plants a stolen crock of leprechaun gold in the soil near Fort Knox to reap what he thinks will be a rich harvest. In tow are his spirited daughter (Petula Clark), a love-struck leprechaun (Tommy Steele) and a bigoted Southern senator (Keenan Wynn) transformed by misbegotten magic. The treasurable Burton Lane/E.Y. Harburg score includes “How Are Things in Glocca Morra?,” “Look to the Rainbow,” “If This Isn’t Love” and “Old Devil Moon.” Watching it, you’ll be in clover. Four-leaf all the way..
