while a pleasant enough musical and what stick with me about this movie be the unexpected comedic chemistry between basil rathbone and a the have be composer and and oscar levant a his assistant . play a high strung and distract artistic type ( a far cry from his more familiar role a either menace villain or the coolly logical sherlock holmes ) and rathbone character look like he couldn not find his way out of bed without help . and that help be starbuck and play with his usual droll humor by oscar levant . upon hire crosby character a his ghost song writer and rathbone introduces him to starbuck by say and he do all my thinking for me . and to which levant responds and ah and it only a part time job . of course this go right past ( or over ) rathbone and who too busy fret about where his next hit song will come from . a another reviewer say and who know rathbone could be so funny . too bad he do not have more opportunity to display his comedic talent .
