I'm gonna have to kill this fucking clown. Welcome to The Losers' Club , asshole! However, his hyperactivity seems to have been toned down in the adaptation.
Richard "Richie" Tozier
Richie Tozier : You punched me, made me walk through shitty water, dragged me through a crackhouse Richie Tozier : I hear the list is longer than my wang. Stanley Uris : That's not saying much. Richie Tozier : Hey Eddie, are these your birth control pills? Eddie Kaspbrak : Yeah, I'm saving them for your sister! Ben Hanscom : I thought you said you wanted to get out of this town too.

Richie Tozier may not be the leader of IT 's Losers' Club, but he's certainly the funniest member, and here's everyone who's brought him to life. Pennywise is definitely the most recognizable character from the IT movies and miniseries, and is always naturally going to get the most attention. Still, the true dramatic center of IT is the Losers' Club, a group of seven people that become friends as children and form an unbreakable bond. It's not quite as clear in the adaptations as it is in Stephen King's book, but there's something particularly special about the Losers' Club characters, who arguably had always been destined for a showdown with Pennywise and the ancient creature hiding beyond that colorful disguise in the sewers of Derry, Maine. Putting aside the most infamous, inexplicable scene from the novel, what the Losers' Club shares is the height of friendship, willing to die to save each other if need be. While Bill Denborough is the official leader of the Losers' Club, it's arguable that Richie Tozier is the true heart and soul of the group.
Richard Tozier is a fictional character created by Stephen King  and one of the main characters of his novel It. The character is a member of "The Loser's Club" and is seen to be the comic relief of the group; however, his loudmouthed antics often get him in trouble, leading to him being called "Richie 'Trashmouth' Tozier" and his friends often using the phrase "Beep Beep Richie" when they want him to be quiet. He was portrayed by Seth Green as a child and Harry Anderson as an adult in the miniseries adaptation of the novel, and by Ankur Javeri as a child and Nasirr Khan as an adult in the novel's television series adaptation.
