Apparently, when "God's Little Acre" first came out, much of it was cut for the theatrical release. Watching the unedited version, one can see why (needless to say, it's all pretty tame to us in the 21st century). Part of it is Tina Louise's very presence - I mean, what man wouldn't want to be stranded on an island with Ginger Grant? - but there's also a scene where Buddy Hackett works a pump for a woman in a bathtub (if that scene isn't a double entendre, then I don't know what is!).
As for the movie itself, this story of a Georgia farmer (Robert Ryan) getting convinced that thar's gold in them thar holes in his garden does quite well. The idea of him tearing up his garden is an effective parallel for how the family gets torn up in the process. As for his friendship with the African-American guy, it's probably debatable whether they were sugar-coating race relations, or if they were encouraging tolerance. There could even be debates about how the movie portrays the South in general (the characters do come across as hicks).
But overall, I recommend this flick. Usually, it would sort of weaken the movie to know that some of the cast members later became famous on TV shows - especially since one was known for seducing romantically incompetent men on a certain island - but they all do very well here. This is certainly a movie worth seeing. And the theme song will probably get stuck in your head. Also starring Aldo Ray, Jack Lord, Fay Spain, Vic Morrow and Michael Landon.
