Well, let me see. This is a comedy without any comedy. This is one of the worst movies that has (Neil Simon)'s name on it. And this is the 1960s' most theatrical cinema I have ever seen!
Come to think of it, the conversations are too long, and not even droll or try to be. (Bud Yorkin)'s direction is anything but cinematic. Moreover, (Lee J. Cobb) was 4 years older than (Frank Sinatra), and he played his father! Not to mention that (Sinatra) himself as the bachelor playboy was 48 years old while his brother, Tony Bill, was 23 (Yes, there are 25 years between them!).
(Sinatra) does an imitation of President Kennedy, and Dean Martin appears in a dull cameo; they seem like inside jokes for Sinatra and his fellows. And the title? Sorry, but I have to suspect a double meaning where the other one is lewd; it could be the 1960s' free swinging spirit, where cheekiness were starting its outburst, to have in the same era other titles for Hollywood movies like Let's Make Love (1960), Sex and the Single Girl (1964).. etc.
So what's here to love? The title's song, it's clever and I loved it, so the music.
(Come Blow Your Horn) is a memory from what looks now as a far faraway galaxy, but it even doesn't represent its best. Seeing it in the 2000s is a history lesson more than an enjoyable time, to assure that the 1960s had weak movies and with big names. Yet at least they were making them that polished; it was nominated for the Oscar of the Best Art Direction-Set Decoration, Color. Anyway, thanks to the TV that keeps transforming the "forgettable" into "unforgettable".
