Thank you very much for all the info (and encouragement!!!)

Btw, I have a copy of the original script and there was indeed a "love affair" between Uncas and Alice filmed but it never made it to the final copy.

It isn't a very long film and imagine that it could have been possible to "fit" this love story in. :D But it is great as it is - Alice is almost too fragile to live and I loved this depiction of her character. My only (small) niggling feeling is that I could have liked to see Uncas portrayed as more interesting character.
