Two acting heavyweights Olivia Colman and David Thewlis are set to deliver what will certainly be exceptionally chilling performances this December.

'Landscapers' is going to be a fascinating watch. The Sky original series is inspired by real events concerning a middle-aged married couple who had bodies buried in their back garden for a number of years.

The unassuming couple are played by Academy Award winner Olivia Colman and Emmy nominee David Thewlis. As we've seen in the past, both play the "accidentally unhinged" role very well, so we're very much looking forward to seeing what bravado they deliver in this miniseries.

Sky released the brand new poster for the series today, which shows the happy couple in each other's arms while sitting on a blood-stained sofa.

As we saw in the previously-released trailer for the series, we're going to delve into the alternative minds of the two lead characters; but the fictional universe which Susan (Colman) and Christopher (Thewlis) have created for themselves will catch up with them eventually as more details about their horrific crime emerge.

The official synopsis for 'Landscapers' is as follows: An exhilarating and darkly funny exploration of love and fantasy starring Olivia Colman and David Thewlis. Mild-mannered husband and wife Susan (Colman) and Christopher Edwards (Thewlis) have been on the run from reality for over 15 years. When Christopher makes a startling call home to his stepmother, their role in a terrible crime that remained undiscovered for over a decade begins to emerge into the light. As the investigation moves forward, inspired by Susan’s obsession with old Westerns and classic cinema, the fantasists cast themselves as Hollywood heroes in narratives of their own invention. Powered by Susan’s extraordinary imagination, Susan and Chris’s fantasy world provides a much-needed sanctuary from real-world horrors and their own clawing guilt, but also threatens to undo them completely.

'Landscapers' will be available on Sky Atlantic and streaming service NOW from Monday, December 6.
