Chosen answer: I believe the film you're referring to is "Equus", from 1977, which received three Oscar nominations, including Best Actor for Richard Burton. I might add that before the film this was originally a play at the National Theatre and then an acclaimed Broadway show, which earned quite a few awards, including awards for Sir Anthony Hopkins.

Chosen answer: The ghost in Three Men wasn't actually a deliberate addition, more rumour than an addition. An example of a supposed addition was a munchkin that had supposedly commited suicide on the Wizard of Oz set and was captured on screen. Many of these high profiled additions are not usually put into films. Most who claim they have stumbled upon something of great interest will generally make something out of what is usually nothing there (like the Virgin Mary in the cheese sandwich). Much like how many people claim to hear and see things in many Disney films. Filmmakers sometimes put little fun additions in their films like visual items or using lines from previous films. However its not their main priority, as I said most of these additions are just coincidence. For more rumours or supposed additions www.snopes.com is a great site for urban legends.

Chosen answer: In the first scene of "The Miracle Worker" (1962), Helen Keller's parents discover she's deaf and blind when they clap and shout at her in her crib. There are two other films with the same plot. Johnny Belinda (1948) starring Jane Wyman and Lew Aryes. A girl living in backwoods rural community, has everyone believing she is dumb. She grows up a wild child, Aryes plays a teacher who realises her condition and teaches her how to sign. The other is the Story of Esther Costello, a young girl is rendered deaf and mute by an accident. Joan Crawford plays a wealthy woman who takes pity on her and takes to the big city to educate her. Both are soap opera dramas.
