Afraid of the Dark (1991)
starring Ben Keyworth, James Fox, Fanny Ardant, Paul McGann, Clare Holman, Robert Stephens, David Thewlis
Young Lucas, an adventurous young boy, is seen as a fearless creature who seems to be in the wrong place, at the wrong time. When we first meet him, he accompanies his mother to a sort of care center for the blind. There are reports of a slasher that is cutting the faces of some of the blind people that attend the center. When he follows one of the women, who leaves nearby, he watches in horror as her face is slashed by the intruder. Lucas flees to the cemetery nearby, where he likes to play. It's at this point that we realize something is wrong with Lucas, who ends up spying on his half sister posing for a photographer. Then, everything changes. The mere reality is that everything one has witnessed is just not so. The fact is that Lucas is going blind if he doesn't have the operation to save his sight. His loving parents, Frank and Miriam, are ecstatic because they are expecting another baby, something that doesn't play well in the young boy's mind. Lucas, who probably feels jealousy toward the unborn baby, thinks of ways of dealing with the intrusion in his life. His obsession with knitting needles prove to be a dangerous proposition.
I've watched this one a number of times. It's quite disturbing yet fascinating, with some parts almost too difficult to watch. (I have poor eyesight, too, so I'm ultrasensitive about that part of the anatomy.)
