Mr Selfridge (Seasons 1–4)

Mr Selfridge (2013) is the ITV costume drama you can watch online on iFILM. London, 1909: a brash American throws open the doors of a department store unlike anything the city has seen.

Harry Gordon Selfridge (Jeremy Piven) believes shopping should thrill like a vice, so he turns retail into theatre — window displays as spectacle, aviators and stars on the shop floor, women welcomed as the guests of honour. Behind the marble, things wobble: his wife Rose endures the affairs, and a weakness for cards and horses keeps dragging the empire toward ruin. Shopgirls like Agnes Towler chase their own shot at the new century.

Across four seasons the show traces the real merchant prince from his 1909 triumph to the wreckage of the late 1930s, drawing on Lindy Woodhead's biography of the man who more or less invented modern shopping. Piven plays him as a firework that never quite stops going off. Stream every season of Mr Selfridge online on iFILM.
