Actor David Morrissey says it is hard to promote The Walking Dead for fear of giving away spoilers to fans.
Morrissey plays 'The Governor' in the show based on the cult comic strip about a group trying to survive the zombie apocalypse.
The return of the third series broke cable viewing records when it was shown in the USA but the English actor refused to confirm whether his character would still be alive for the fourth series.
The Walking Dead, Season 3 Part B returns on Friday 15th February at 10pm on FOX.
