The plot's something about a go-between dog that gets lost from its two smuggler gangs and finds a home, sort of, with a young couple.
Granger strives mightily to put the mad in madcap, but unfortunately it's too mightily. His incessant mugging in the latter half not only gets tiresome but amounts to unfunny desperation. Actually, the real problem with this misfire--as others point out--lies with director-writer Beck. In short, the screenplay is much too congested, probably to insert the many first-rate supporting players who could have provided real laughs if properly directed and defined. Instead, the likes of Leonard, Conreid, Cook, Jenkins, are largely wasted by a turgid screenplay. Only grouchy Demarest and sarcastic Gillmore manage to register. Winters' comedic talents are also largely wasted as the neglected wife, a role a hundred lesser actresses could have filled.
Looks like the producers were intent on promoting Granger's career since he monopolizes the screen time. Looks also like he was trying to expand his range into comedy. Too bad the package doesn't work. At the same time, judging by his credits, the actor quickly returned to drama, and being the bobby-sox idol he was so good at. Anyway, I hope they gave Archie triple treats for his lively tail-wagging turn. He may not be a glamorous Lassie, but he'll sure do.
