Disney films must be run on the tears of children (and me)
This could be a big list
In Dumbo when he visits his Mum when she's locked up in the caravan and she puts her trunk out through the bars and rocks him
The Fox and The Hound when Todd is taken out into the woods and set free and she says that heartbreaking poem to him
Neuvo Cinema Paradiso (original version)
Black Beauty, Donnie Darko, Marley and Me, The Man From Snowy River 2 (when his pony is killed), Prancer
basically any film where a pony or horse dies
