i think the movie Gladiator would best represent the summoner because the bad guy in the movie is a bad person, he is creepy,a lair a murderer and a sneak. The summoner is like that as well in some ways.
Joaquin-Phoenix-Commodus-Gladiator: In my opinion, one of the absolute best villains. He makes my skin crawl.
gladiator thumbs down
Joaquin Phoenix as Ferrovax (mostly because of the intense eyes, and this role)
