EXCLUSIVE: Up-and-coming German actress Bella Dayne has joined the cast of Guerrilla, a six-episode drama from American Crime creator John Ridley.

The mini-series, which is currently filming in London, will see Dayne join Idris Elba and Freida Pinto in a story set in the 1970s in the UK capital during the birth of the Black Power movement.

Co-star Elba also exec produces the program through his Green Door Pictures banner while ABC Signature Studios produces.
