In June 2012 Horgan was part of the ensemble cast for the pilot episode of "Psychobitches", shown as part of Sky Arts 1's "Playhouse Presents" strand. In the sketch show, famous women from history are psychoanalysed by Rebecca Front's therapist; Horgan played the novelist Jane Austen in the pilot, and later characters included Eva Peron, Cleopatra, Boudicca and Carmen Miranda. Two series of "Psychobitches" followed; the first was shown in May 2013, and the second in November 2014. Horgan played a supporting role in the 2018 dark comedy film "Game Night" as Sarah, a newcomer to the group of friends unwittingly roped into the game.
