Extended history b/c this got more views than I thought:

The filmmakers decided to film some scenes to change Draco's storyline ending and give him the redemption arc many fans (including myself) believe he should have had. They then cut this part out for unknown reasons.
The cut they were going to go with, and then one I tried to piece together in this vid, has Draco throwing his wand to Harry when it's revealed that Harry's alive.
