Jason Ritter received the script of the "Joan of Arcadia" (2003) episode "Death Be Not Whatever" on September 11, 2003, the day his father John Ritter died. It originally aired on November 7, 2003, only two days after the death of his paternal grandmother, Dorothy Fay.
He and his "Joan of Arcadia" (2003) co-star Chris Marquette also starred together in Freddy Vs. Jason (2003)
Since actor Jason Ritter hails from a long line of successful entertainers, it seemed only natural that he would eventually try his hand at performing. The son of late Three's Company star John Ritter and the grandson of Hollywood Western star Tex Ritter, young Jason Ritter has proven more than capable of carrying on his family's impressive showbiz legacy with roles in such features as Mumford and Freddy vs. Jason. Born in Los Angeles in February of 1980, Jason Ritter made his screen debut opposite father John in the 1990 made-for-television L. Frank Baum biopic The Dreamer of Oz. Though he remained relatively inactive on the screen for much of the 1990s, Jason Ritter continued to train as an actor at both New York University and London's Royal Academy of Dramatic Arts before founding New York City's Irreputable Theater Company. Subsequent roles in the MTV series Undressed and the fantasy-flavored CBS drama Joan of Arcadia quickly elevated Jason Ritter to teen-icon status. A segue into feature territory followed with parts in Freddy vs. Jason (2003) and Swimfan (2002), with his continuing role on Joan of Arcadia serving well to balance his feature and television careers. In 2004, Jason Ritter's performances in the made-for-television Who's Your Mama? and the Hilary Duff movie Raise Your Voice were quick to follow, and Jason Ritter could also be seen opposite such screen heavies as Steve Coogan, Tom Arnold, and Maggie Gyllenhaal in director Don Roos' ensemble comedy drama Happy Endings.
