The former "Seinfeld" cast member and "Dancing with the Stars" contender will play Kit Sterling, a producer who approaches Erica Kane, played by Susan Lucci, to make a movie based on a book she has written. O'Hurley's first episode on "All My Children" is scheduled to air Sept. 12.
In addition to his work in prime-time television, O'Hurley has also played good and evil twins Keith Lane and Jonathan Matalaine on "Loving" and character Greg Bennett on "General Hospital."
ABC recently announced the long-running soap opera will continue airing on the Internet after it wraps up its broadcast run this fall.
