Hey, so this is kinda old news so some of you probably already know this, but well if you don't keep on reading.
So in the deathly hallows part 2 at the end there would've been a scene (when they found out Harry was alive) where Draco turned against Voldemort and saved Harry the last seconds. He ran away from his parents screaming 'POTTER!' and helped him, even though Voldemort probably would've killed him.
They deleted the scene because they thought the Harry Potter fans wouldn't like that because there are many Draco-haters.
I just thought you guys should know. :)
