See No Evil (Blind Terror)
1971

Poor old Mia Farrow. Not only does she get beaten up, kidnapped, knocked off a horse and nearly drowned in this film, but to top it all off, she's blind. Yes, it's that old chestnut, the "disabled person in peril" film.
We'll gloss over the fact that Ms Farrow's "blind acting" (if that's what it's called) is truly horrendous - she makes eye contact with everyone she's talking to, and seems to navigate round objects with considerable ease considering the blindness is a relatively new thing.
Instead, we'll concentrate on the rest of the film, which is actually quite good. Mia , recovering from the horseriding accident which has left her without sight, goes to stay with relatives in a big country house. While she's out for the evening, someone breaks into the house and massacres the rest of the family. She comes home and goes to bed, not realising that the family's bodies are lying prone all around her.
Some clever camerawork actually lets realisation of what has happen dawn on the viewer quite slowly, and we're only just one step ahead of Mia as she makes her shocking discovery.
The killer is a porn loving, violent movie-watching cowboy-boot wearer (aren't they always?), who's only motive appears to be that at the beginning of the film, the father of the house has the temerity to splash said boots as he drives past in his Jag. Remember this the next time you're driving in the rain.
Of course, Mia escapes the clutches of the killer (it wouldn't be a particularly long film if he grabbed her straight away), but only after treading on a load of broken glass (ouch!). Suspicion then falls on a local band of gypsies, who respond by kidnapping Mia and locking her in a shed on a building site (like you do).
There's a couple of obvious twists at the end and it's not for the squeamish, but this ain't a bad film at all. And any film which has a blind person riding a horse full pelt into a large tree branch (bang - thump-whinny!) deserves to be seen, just for the sheer bad taste of it all.
