J.T.M. in the New York Times (November 28,1936):

A slightly daffy cinematic item of absolutely no importance, "Love on the Run," is currently at the Capitol, with Clark Gable, Joan Crawford and Franchot Tone in roles that by now are a bit stale. In all good conscience, the film ought to bow, in turn, to several distinguished antecedents, for it has borrowed liberally here and there of tried and true screen devices and situations.

Mr. Gable and Mr. Tone are allegedly rival foreign correspondents for New York newspapers, but Mr. Tone is too easily outwitted to be called a rival. Their current assignments are a stratosphere flier who turns out to be a spy (Reginald Owen), and an heiress (Joan Crawford), who is scheduled to marry royalty, but on reconsideration turns out her prince.

In the course of helping Miss Crawford escape Mr. Gable unmasks the spy, leads the heiress over the face of Europe at a dizzy pace by air, auto and oxcart; invades Fontainebleu for a night's lodging, arousing new hallucinations in the mind of the unstable caretaker; and eventually leads Miss Crawford to the altar after a characteristic interlude of trumpeted vituperation on his part and scorned woman fury on hers. Mr. Tone, meanwhile, tags along, permitting himself to be hoodwinked thoroughly from London to Nice.

Honors must go to Mr. Tone, Reginald Owen and Donald Meek. W. S. Van Dyke has injected a few of his own tested touches, and some in the Rene Clair and Frank Capra manner, with a resulting mad pace and pleasing familiarity for the audience.

Howard Barnes in the New York Herald Tribune (1936):

    A lot of gay nonsense has been strung together....a fantastic and insubstantial narrative, with the result that it is almost continuously amusing and frequently hilarious... Miss Crawford, of the big eyes and flowing hair, turns in a surprisingly volatile and amusing performance as the heiress.
