Yep, that's the one. I do remember watching this on KTLA Channel 5 in Los Angeles every Xmas Eve.
This was the mid-70's so I was about 7 or 8 years old.
Yep, i'll never forget the 'leech' scene..it grossed me out!
Still, I thought it was an interesting movie overall and wonder why they have never shown it on tv since then.
I too remember watching this on Xmas Eve in the '70s. I remember the scene too but they were Bot flies not leeches. Look up 'bot fly removal' on g00gle and you will be grossed out all over again!
This means my post finished two seconds ago.
Ah yes, I also remember they kinda looked like worm-like larva. Nonetheless, still gross!
In the documentary WINGS OF HOPE you get to see what her infestation would have looked like.....unbelievably disgusting and so much worse than what they used in the film.
