Describing his own work as "well-observed fiction", Nicholas' film style incorporates real life subject matter with the sensibilities of still photography. He trained as an anthropologist before joining the BBC as a radio producer, and went on to create three TV series for the BBC: "Washes Whiter," "Signs of the Times,"
and "From A to B." Following his BBC work, Nicholas directed his first feature, Unmade Beds, produced by Chelsea.
Acclaimed for "his extraordinary ability to distill something quirky from ordinariness," in the words of David Reviews UK, "Barker is the
creator of masterful miniatures of understatement."
His wealth of advertising directorial credits include Centraal Beheer, Nike, VW, Heineken, Dyson, McDonald's, Volkswagen and Carte D'Or.
