Simon Lewis is one of the lead male roles within the film.
Simon is described physically as tall, with brown hair and brown eyes. Simon also wears glasses. Simon is also ‘a bit of a geek’ and is part of a band (one that never has a name).
In the film, Simon is played by Robert Sheehan, an Irish actor.
Simon is openly geeky, and is the bassist in a garage band. He likes to play Dungeons and Dragons, and when he is introduced to the Shadow World he refers it to the game, much to the horror of Clary and Jace. He is best friends with Clary, and will do anything to help her and will stand by her side. Simon quickly develops feelings for Isabelle and they begin a relationship. Simon is also turned into a vampire later in the series.
