Up is a hit Disney/Pixar movie that came out in 2009 and melted hearts everywhere. In the movie, an old man named Carl loses his wife. He and a boy scout named Russell, who turns up on his porch out of nowhere, lift his house into the air by tying balloons onto it. They then travel to South America and back, trying to fulfill the dream of Carl's wife. I won't ruin the rest of the movie, but it's the sweetest thing ever.
Of course, if you've seen the movie, you know that Carl's wife's name was Ellie. There is a montage at the beginning of the movie that details their life together and ends with her passing away. It's a tear-jerker every time people watch the movie and it's only going to get even sadder from here.
