Clare Trevor had decorated many films in a range of roles which commonly portrayed her as a tough broad. She was able to assure her husband, producer Milton Bren, that she was also qualified to perform in comedic parts, and the result is his bankrolling of this action-comedy hybrid: BORDERLINE, which features Fred MacMurray and Trevor as undercover narcotics operatives working for different agencies with the same target, but unaware of each other's placement. The film just misses working on both levels of drama and comedy; the scenario by veteran Hollywood light musical scriptor Devery Freeman cuts its chances, but improves during the second half. MacMurray, generally unrecognized as a cinema tough guy, shines and teams well with Trevor, who in fact does demonstrate that she can do light comedy.
