South of Panama (1941)

A modest but decent espionage drama. Government scientist Paul Martin (Hugh Beaumont) has developed a new secret camouflage paint and is heading to Panama, but enemy agents want that secret for themselves. Paul's sister Jan (Virginia Vale) is warned agents are waiting for her brother and causes a distraction with stranger Mike Lawrence (Richard Pryor).

Lawrence, whom the rather clueless agents think is Jan's sister, gets drawn into the action which includes some fairly low-octane car chases and a few fumbling fight scenes. Jan meanwhile puts on a black wig and becomes a Latina singer and becomes "unrecognisable" despite her awful accent...

An enjoyable little film which makes little sense if we are to be honest, if the scientist's formula was so valuable why would he be allowed to travel without any protection? However if the viewer can get over that they'll find a fast paced drama, maybe few surprises but well executed.
