Another trivia (but one with no answer known)

[Fred588]

Posting this as a separate thread because the current trivia thread is still unsolved.

This is a trivia-like question but one for which I do NOT know the answer:

I now that Vera Miles appeared in two movies (that I know of) that technically had quicksand, but she was only seen IN the quicksand in one of them. She was IN the quicksand in Tarzan's Hidden Jungle and APPARENTLY IN the quicksand in Psycho. There is a scene in Psycho in which a car is sunk, presumably with the deceased victim inside. But my question here, for which I'd really like to know the answer is what mainstream actress has appeared in the most quicksand scenes. For purposes of this question I mean appeared in mainstream, or at least minor mainstream scenes. That is to say, scenes produced by producers in the quicksand community do not count.

Vera Miles played the sister of Janet Leigh in Psycho. Janet was the one in the trunk so Vera has only sunk once although yeah, she's been in two movies with quicksand. As the the actual answer to the trivia you posit - I don't know but it's a good study. Might be fun to see if we can figure it out. Why don't you repost this question to general discussion and get everyone involved?
