Over the holidays, I somehow stumbled across what I can only assume was an edited version of Heidi. Yes, that Heidi, with Shirley Temple. Now, I say "assume", because I've never seen the movie myself. This was my first introduction to it. Given the age of the movie, I'll assume it's past the statute of limitations on spoilers for the ending, which is what was edited (this was on one of the cable movie channels, not sure which one).
According to the version I was watching, Heidi is being taken away by the Governess, and her Grandfather finds her and tries to save her. The Governess starts yelling that "her" child is being taken, so the police come, and take them all to the station. Grandfather is taken down to the cells, while the Governess tries to take "her" Heidi away. Heidi fights against her, and tells them to call Sesemann, who would tell them that the Governess wasn't her mother. The Governess tried to tell them she was lying, but they said they'd call Sesemann anyway. Cut to a commercial, and we come back to... Heidi living happily with her Grandfather, and the Sesemanns are coming to visit.
My mother came home, and I told her that I was very dissatisfied with the ending, because I wanted to see some sort of conclusion to the attempted kidnapping by the Governess, and her Grandfather to get full and complete custody of her. My mother just looked at me, and told me that that did happen, as far as she remembers. So I have to assume that there's a scene that goes between those scenes around the commercial break.
On the flip side, though, is Legend. There are (at least) 4 different versions of the film: The American theatrical version, European version, television version, and Director's Cut. As far as I've been able to research, none of them have all of the existing footage (a fire apparently destroyed some of the sets and recorded footage during filming). However, the television cut is almost 6 minutes longer than the American theatrical version. There's scenes in the theatrical that aren't in the TV version, but the TV version seems to be closer to the original intent (which was 125 minutes long, and even the Director's Cut isn't that long).
