Dexter viral makes viewer prime suspect

Users take the role of a journalist asking questions to a police chief. They can record their own question and statement using their microphone or webcam and incorporate these into their personalised video.

FX UK, owned by Fox, will run the campaign on its website and an email will alert users who participated in last year's 'The Dexter Treatment' viral.

The controversial Dexter Treatment viral, also created by Ralph, was launched to promote the first series of the show in 2007.

It made people feel that they were the next victim of a serial killer on the rampage and attracted global media coverage, complaints from the public and calls for a police interview for Ralph's directors.

Cecilia Parker, communications director of FX UK, said: "The success of our first viral is apparent a year later so coming up with something special and new for season two was a challenge we knew Ralph would meet head on.

"The result is a fiercer more compelling interactive spoof which we think fits perfectly with the new themes. We're confident it will help deliver our marketing messages about the show as well as being an engaging user experience for fans."

'Dexter' stars 'Six Feet Under' actor Michael C Hall, who plays a forensic detective in Miami leading a double-life as a serial killer under the alias Patrick Bateman -- the name of the Genesis-admiring psychopath in Brett Easton Ellis' 'American Psycho'.

The second season also stars British actress Jaime Murray, who is best known in the UK for appearing in the BBC's 'Hustle'.
