Frank Sinatra spends most of his time in Come Blow Your Horn looking like he's waiting for director Bud Yorkin to infuse some inspiration into the film. Sinatra doesn't get his wish, but he works like an old pro in this Neil Simon comedy about a playboy getting pressure from his conservative, Jewish father (Lee J. Cobb) while simultaneously feeling threatened by the man-on-the-make moves of his competitive younger brother (Tony Bill). The film is fun and everyone in it is fine, but the production lacks the snap it ought to have. Sinatra seems especially good-natured in scenes where the cocky Bill treats him like yesterday's papers. --Tom Keogh
