I would prefer if most of the cast stays the same, doubt it but we shall see how that goes. Here's my other cast choices, not necessarily have to be in the movies.
Max Dillin/Electro: Matt Dillion (Crash, Something About Mary)
Pr.Allistar Smythe: Chris Cooper (Bourne Identity)
Kraven The Hunter: Oded Fehr (The Mummy Movies, Deuce Bigelow)
Mac Cragen/The Scorpion: Peter Stormare (Armageddon, Bad Boys 2)
Kletuis Cassidy/Carnage: Sam Rockwell.............or......Jim Carrey
-I honestly think Carrey would be great in a serious dark role.
Adrian Toomes/The Vulture: Ben Kingsley (Schindler's List, Rules of Engagment)
Quentin Beck/Mysterio: Sam Neill (Jurasic Park, In the Mouth of Madness)
The Chamelion: Billy Zane (Titanic, Phantom)
The Kingpin: Michael Clark Duncan *Of Course* (Daredevil)
Ned Leeds: Scott Melchowitz (Eurotrip, Mean Creek)
