Hayley Atwell, Jason Flemyng and Lenora Crichlow are to star in the second series of Charlie Brooker's Black Mirror.
The dark drama anthology will return with three new films on Channel 4 in the near future.
'Be Right Back' involves a terrifying twist on the world of social media, with Martha (Atwell) using a new online service to 'communicate' with her dead boyfriend Ash (Domhnall Gleeson).
'The Waldo Moment' will star Daniel Rigby as Jamie Salter, a failed comedian who becomes the voice of Waldo - an anarchic animated character on a satirical late-night topical comedy show.
Salter's life spirals out of control as he becomes frustrated with the world of politics and blue bear Waldo becomes a very real candidate in the upcoming by-election. Jason Flemyng also stars as TV exec Jack Napier.
Being Human actress Crichlow will play the amnesic Toni - a woman on the run from a hostile figure (Michael Smiley) - in third instalment 'White Bear'. Ian Bonar (Skyfall) and Tuppence Middleton (Spies of Warsaw) will also star in the dystopian thriller.
Series creator Charlie Brooker previously hinted at what to expect from series two of Black Mirror.
"Like the last series we've done three stories that are three different genres," he said in December. "We've also got all sorts of unpleasant things and also one of them is very sad."
