Broadchurch series one focused on the search for the boy 's murderer by detectives Alec Hardy -LRB- played by David Tennant -RRB- and Ellie Miller -LRB- played by Olivia Colman -RRB- . Chibnall was inspired by the Jurassic Coast of Britain to set his crime drama in a fictional , close-knit small town in Dorset .

Principal photography began in August 2012 , with location shooting occurring primarily in towns and villages in Dorset , North Somerset , South Gloucestershire and Bristol .
