Is 'Jonah' part of a trilogy?

I watched this movie in 1977 or '78; found it brilliant, and moving.

It was screened at a US college, in the context of "alternative movie" nights.

I seem to recall it was presented as part of a trilogy. I can't remember if the presenter grouped it with other movies by the same director, or had grouped it with movies by others.

Is anyone here familiar with this question? Is "Jonah" sometimes perceived as belonging to a larger trio of films, either by intention of the creators, or simply categorized that way by film critics?

Thanks,
