Its a Wonderful Life
Death Wish
While not a remake of Its a Wonderful Life the 2000 Nick Cage movie The Family Man borrows from many of the themes of Its A Wonderful Life and A Christmas Carol while being a completely original scrip. This movie is one of my top 20 favorite movies.

Made for TV remake (1977) called "It Happened One Christmas" starring Marlo Thomas and Wayne Rogers. Marlo Thomas was the main character. Saw it first before discovering the original and there's no going back.
Its a Wonderful Life
Did you ever see the “Lost Ending”?
