Filmed on location, Hawaiian Buckaroo is certainly the most novel of the Smith Ballew westerns. Pineapple plantation worker Jeff Howard (Ballew) and his pal Mike (Benny Burt) go to work on a cattle ranch run by haughty Paula Harrington (Evelyn Knapp). It doesn't take long for our heroes to figure out that Paula's foreman Riga (Georges Regas) is a crook. Acting quickly, Jeff and Mike prevent Riga and his confederates (Harry Woods and Pat O'Brien -- no, not that Pat O'Brien) from depleting Paula's stock for their own purposes. Ethnic humor is provided by black actor Fred "Snowflake" Toones, while Honolulu cabaret entertainer Princess Luana shows up unbilled.
