As far as Candy is concerned, see the wonderfully abrasive review on Jabootu:

It not only had Ringo, it had Walter Matthau, Richard Burton (!!),and Marlon Brando (!!!). I know for a fact that it came out on DVD – I saw the box.
There are plenty of movies that have completely, utterly disappeared – many of them deservedly (consider The Magic Christian, which, like Candy, had Ringo in it and resulted from the workj of writer Terry Sothern. This one, unfortunately, I have seen. As Frankenstein’s monster said at the end of The Bride of Frankenstein, “We belong dead”.
