One of my mother's favorite movies is a 1967 film called, "The Honey Pot." I saw it a few times when I was younger but didn't remember it well. Reading "Volpone," reminded me a lot of that old movie. And, as it turns out, for good reason. The movie was meant to be reminiscent of the play, part of the action is based on "Volpone."
Although the plots diverge a good deal, they both deal with an apparently wealth man and three potential inheritors. Both are also comedic, if a little dark.
You can actually watch the entire movie on Hulu if you so desire (it doesn't suck). I didn't remember at all, but the first scene of the movie shows the wealthy man watching a theatrical performance of "Volpone," so at least that might be worth checking out, if not the whole movie.
