been trying to find a movie I saw when I was young. A girl went to stay with her cousin I believe. She did weird things like made spots or her in a picture. But a one point she attacked her in a dark room while she was developing film. Her eyes turned red and she was a witch. I think she chased her cousin and boyfriend in a car at the end but ended up crashing and dying I think. I have looking for this movie for years I sure its stupid now but it scared the crap out of me when I was young. If anyone can help I would apprecite it.
This could possibly be Wes Craven's 1978 TV movie called "Stranger In Our House".
A young girl's cousin goes to stay at her house and suspects her of being a witch. Her suspicions turn out to be true.

It also goes by the name of "Summer Of Fear", it stars Linda Blair.
Another possibility might be "Sarah's Initiation" but it's a bit more like a "Carrie" rip-off.
