1st pairing of dir. Nelson and EP. GN also has screenplay credit (with another).

9 songs in the Soundtracks: all but 1 sung by EP. 3 additional songs cut from the film.

No exotic location shoot here; this looks like a studio job.

Having EP in a dual role as the army guy and the blonde backwoods cousin is no thrill. And when they both appear in the same shot, we don't get any slick technology making it happen; there's definitely a double involved.

Just another EP film. Unfortunately, another follows immediately.
