Jacob Shemkovitz’s review published on Letterboxd :
An interesting relic: One of Fannie Brice's few films. I read that she was a Ziegfeld Girl known for her comedy and songs, and that Streisand's Funny Girl was based on her life (haven't seen it).
This movie is soaked in "ethnic comedy" - Fannie plays up the Yiddish accent for laughs, and her brother is a straight-up stereotype. Brice is funny here, but the story is flat. The songs are mostly uninteresting diegetic performances, with one or two amusing production oddities. Armstrong plays a convincing dumb boxer (oddly paired with Brice's too-smart showgirl businesswoman), but the performances of the boxing matches are odd and confusing.
I have no idea what the title has to do with the film.
