A little nagging thought
This isn't a criticism as I really enjoyed the film but several times, Martha (and even once or twice, Honey), sounded exactly like Ruth Gordon to me.
I don't recall ever having that thought before with any other film I've seen, as I always felt Ruth Gordon had a very unique voice and speech pattern/delivery but, like I said, a few times they sounded just like her. I can't see it being imitation as Ruth seemed more a known commodity a few years later. Is Ruth's voice actually a specific accent that they are also using or am I confused as to how I heard them? Did anyone else hear it?
