Distinguished as the first sound Western film shot in Technicolr, with director Curtiz juggling color, music, dialogue, and the temperamental lead from vaudeville, Frank Fay, who had played the master of ceremonies of the revue film Show of Shows of 1929. An atypical Western, Under a Texas Moon is full of fiestas and beautiful ladies fighting over its singing hero, who renders the title song frequently.
“A light, pleasing talker-singer in all Technicolor of a Western sort, planted on the messican border, giving plenty of flash in ensemble scenes of color, with an unexpectedly smooth performance by Fank Fay in his Don Juan way standing out and carring weight, making this a de luxe programmer that is apt to beat the average gross anywhere the strong lean is toward westerns at present”.
