The Alternate Ending
So I noticed the Alternate Ending page has been edited once again, but this time it's been edited to try and say it never existed.
As a New Zealander, who vividly remembers their parents (and later myself) renting this on VHS as a child many many times (family favorite film) from the local video store, I can say that the Alternate Ending with Josh turning around to see the 'new' Girl in class is REAL and does exist. A lot of people my age who I have talked to over the years, also remembers this ending when brought up in discussion.
The editing of the page suggesting someone wrote to Tom Hanks and Penny Marshall doesn't mean anything, because they were not in the scene in question, so unless they were on set at the time (highly unlikely) they wouldn't have any idea of it. It could well have been a pick up scene.
In order to find it, you'd have to find an original first release VHS tape from New Zealand. Not a simple task I tell you, as I have been on the hunt for many a years.
The person you need to contact is David Moscow, the actor who played the Young Josh.
