"The Magic Bow" is a fictionalized costumer about the life and loves of 19th century violin virtuoso and composer Niccolo Paganini as played by Stewart Granger. Granger looks the part and plays it well. Basically, 'The Magic Bow' is a well-acted, beautifully scored, rags to riches love story. On a technical level, Stuart Granger impressively does all the violin finger movements and bow strokes himself, all in synchronization with the musical selections, which were actually played by the great Yehudi Menuhin. Phyllis Calvert has the thankless role of the woman who redeems him by arranging for him to play for the Pope.
