Actually, NBC's Warren Littlefield proposed a series of made-for-TV movies, similar to what NBC was doing with
Perry Mason. The offer wasn't simply one movie to tie up loose ends.
And as far as palm trees in Collinsport goes, once and for all let's get real - if one honestly thinks about it, they're probably quite appropriate. Yes, Collinsport is in Maine, a state where palm trees shouldn't be likely to be seen. However, Collinsport is hardly the typical Maine locale, now is it? I mean, the grass stays green all year round, the never falling leaves stay fresh and green on the trees all year long - even the ivy on Collinwood itself is some unknown species of evergreen. If palm trees would be likely to be spotted in anywhere in Maine - lo, in anywhere in New England - it would certainly be in Collinsport! Their presence would merely be perfectly in keeping with all the other extremely odd flora of the region.
And I say not only palm trees, but bring on the coconut tress, the banana trees, and, yes, even the cactus! They should all be seen in Collinsport all year long!!
