Norman Bates wasn't really a 'Psycho,' guys.  He was just a love-lorn teenager!  At least, that's the story A&E will tell in 2013, when its prequel TV series 'Bates Motel' explores the early years of the young 'Psycho' killer, particularly his teen years in high school.  Former 'The Killing' star Richard Harmon is the latest to join the cast of the forthcoming series, playing Bates (Freddie Highmore)'s high school rival, but what could have possibly come between them?

Someone better get Alfred Hitchcock on the phone, before there's a 'Killing' at the 'Bates Motel.'  According to TVLine, former 'The Killing' star Richard Harmon (Rosie's schoolmate, sometime lover) has joined the cast of A&E's Norman Bates prequel 'Bates Motel' as Richard Slymore, high school rival to Freddie Highmore's Norman.  Seen as the artsy big man on campus, Harmon's Richard Slymore will come into conflict with Norman when his girlfriend finds herself drawn to the troubled youth's presence.

Developed by 'LOST's' Carlton Cuse, ‘Bates Motel’ takes a kind of ‘Twin Peaks’ meets ‘Smallville’ approach to telling the back-story of Alfred Hitchcock’s ‘Psycho’ killer Norman Bates (Freddie Highmore), focusing on the killer’s days as a boy and how his life with his deranged mother (Vera Farmiga) and her lover drove him mad, eventually turning him the killer we know from Hitchcock’s film.  'LOST's' Nestor Carbonell will also take part in the series as a less-than-savory sheriff.

What do you think?  Do the latest castings for 'Bates Motel' get you excited for the prequel series?
