Richard "Richie" Tozier is a fictional character created by Stephen King and one of the main characters of his 1986 novel It. The character is a member of "The Losers 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 1990 miniseries adaptation of the novel, and by Ankur Javeri as a child and Nasirr Khan as an adult in the novel's 1998 television series adaptation. He was later portrayed by Finn Wolfhard as a child and Bill Hader as an adult in the 2017 film and its 2019 sequel. Source: Wikipedia (en)
