Jeremy Piven is to return to the shopfloor after ITV bosses ordered a further series of drama Mr Selfridge.
The Entourage star will reprise his role as the flamboyant and visionary American entrepreneur Harry Gordon Selfridge in the period drama, which also stars Samuel West, Zoe Tapper and Frances O'Connor.
Jeremy tweeted his excitement over the news: "Proud to say we will be back for a second season."
TV bosses teased that "some exciting new characters" will join Jeremy for the second season, set against the backdrop of the First World War in 1914.
The ten-part run will begin filming in April in London and Kent, and will be screened next year to mark the centenary of start of the war.
The Sunday night hit was launched last month and is the station's biggest new drama for almost two years, pulling in up to 9.5 million viewers.
Acting director of drama commissioning Steve November said: "I am delighted to be re-commissioning ten new episodes of Mr Selfridge from ITV Studios. It is ITV drama at its best and we are looking forward to spending more time with the wonderful characters."
Kate Lewis, executive producer for ITV Studios, added: "The story of Harry Selfridge, his family and colleagues has drawn in a strong drama audience and we are delighted by the response. The second series will allow us to build on this success and it is a fantastic opportunity to focus on 1914 during the centenary of the Great War."
