I had always known about the scene where Peter (Andrew Garfield) sobs over Gwen's body - starting at 1:34; but I came upon this included alt. ending where his father shows up in the graveyard about a year after her death. Peter has been standing vigil all through the seasons at her grave, and thinks his father is dead, so when his father shows up at Gwen's grave (scene starts at 4:40) and tells him he is back because he knows Peter needs him, his genuine anger and sobs wracking his body as he hugs his father are heartbreaking. I always loved Andrew Garfield, and he plays this brilliantly...I think he is one of the most sincere, best criers in film today. Enjoy!
