Nearly as loose-plotted as you could get, MONKEY BUSINESS is a rambunctious outing for the
Marx Brothers in their prime. It was the first Marx Brothers comedy to be written directly for the screen -- not an adapted stage show like
Animal Crackers -- that looks like it could have been shot in one long take through a security camera. This is fluid and fun, with some bits that could only have worked due to cinematography and editing (the mute Harpo "singing" like Maurice Chevalier thanks to a full-sized record player secretly strapped to his back), even if the storyline is nothing but a weak bridge to get from one Marx bit to another.
This is zany stuff, with only a few slow spots during the requisite musical numbers (a chronic ailment in Marx movies). Monkey Business and its follow-up Horse Feathers are probably the most a lot of young viewers will get to see of Thelma Todd, a sexy and funny comedic actress (the "vamping Venus") of the 1930s, who is seemingly able to hold her own against Groucho -- not an easy feat -- in her role as the gangster's restless wife. Todd died mysteriously at age 29, in what may have been suicide or a mob-connected murder, still one of Hollywood's most tantalizing unsolved mysteries.
