What would be some things that could improve each respective series? (In a comedic way.)

Harry Potter: Dave Chappelle Script+AVPM/Original HP Plot+AVPM Songs+Original Harry Potter Cast.

Twilight: Original Twilight plot (aside from Bella randomly getting hit by a fully loaded fridge every 10 minutes)+Everyone is played by Chris Tucker

Twilight: Remember that first Biol lesson when Edward wants to rip her head off and drink all her blood? Yeah, that happens.

Harry Potter: See AVPM
