The two stars of creepy thriller The Following have admitted that the show gives them nightmares.
Kevin Bacon and James Purefoy say their characters stick with them after work and British actor Purefoy said playing a character that not only celebrates death but finds great beauty in it brings fretful nights.
And Jessica Stroup, who is new to the series, says she can sleep well, but she is watching her surroundings more carefully while awake.
Bacon plays former FBI agent Ryan Hardy, on the trail of a sadistic serial killer played by Purefoy in the Fox series, which attracted negative attention for its violence in its premiere season last year, but also had strong ratings. It returns for its second season on Sunday.
