Despite also being overseen by the executive production team, producers and directors cast the recurring characters for their own respective stories. Doctors also features guest stars in each episode, with examples including Leah Bracknell, Emilia Clarke, Alison Hammond, Ruthie Henshall, Jamelia, Claire King, Joe Pasquale, Eddie Redmayne, Lisa Riley and Sheridan Smith. With each new block, a noticeboard on the set is updated with photographs of the guest actors for that block. Series producer Lloyd estimated that at least 800 guest stars are contracted per year. Owing to the large number of actors who have made one or more guest appearances, Doctors gained a reputation for becoming "a British actor's rite of passage".
