i hat finian rainbow . all the song be forgettable and most of the cast be so so . coppola unimaginative handling of the dance number be also a big problem . the material have date badly too and so the director should not be blame for everything that be wrong with this production . the awkward combination of preachy social commentary and irish stereotype do not work for me . it be fred astaire last musical and and he be good in the starring role and but petulia clark have zero star quality ( i can see why she never become a major movie star ) and and don franck be an odd choice for a leading man . tommy steele be charm and if a bit too broad . coppola do not learn his lesson ( the way he edit this movie be particularly embarrass ) and and he return to the genre in the 80 with two mega bomb and one from the heart ( 1982 ) and the cotton club ( 1984 ) .
