I'm searching the font of the end credits from Harry Potter and the Deathly Hallows Part One. I think it's the same font used in the end credits of HP7 Part Two.
You can watch the credits here:

Packard Antique  Sugerida por SamSSpade 

What's shown in the picture here is actually from the end credits of "Harry Potter and the Deathly Hallows, Part TWO." In that one, I'm sure the font used for the credits in Part Two is likely a variation of Packard Antique.
