EXCLUSIVE: John Asher’s comedy I Hate Kids has added Better Call Saul‘s Rhea Seehorn and Witches of East End‘s Rachel Boston to its cast that already includes Tituss Burgess, Tom Everett Scott and Beth Riesgraf.

The film, which started production on July 10, follows Scott as Nick Pearson, a successful author who always has hated kids and is about to finally settle down with the perfect match. However, on the night of his wedding rehearsal dinner, 13-year old Mason (Julian Feder) shows up claiming to be his son. How does the kid know this? Because self-proclaimed psychic the Amazing Fabular (Burgess) says so. The trio set out on a journey to find Mason’s mom and, in doing so, learn about Nick’s past.

Boston will play Nick’s fiancée  Sydneyof, and Seehorn will play her sister Kelly. I Hate Kids is co-written by Frank Dietz and Todd Traina and co-produced by Traina and Rachel McHale.

Boston’s deal was brokered by John Carrabino Management and the Gersh Agency, and Seehorn’s was by Randi Ross of Phoenix Artists and Alissa Vradenburg of Untitled Entertainment.
