For those in the UK, Entourage airs on ITV in September!
UK terrestrial ITV's digital spin-off ITV2 has jumped head first into US acquisitions and pulled off something of a feat by nabbing the multi-channel rights to hit HBO comedy Entourage.
The first two seasons of the Hollywood-set behind-the-scenes comedy/drama, now in its third season in the US, will kick off back-to-back on September 10 in the 22.00 timeslot.
In some ways, Entourage, executive produced by Mark Wahlberg, picks up where HBO's Sex and the City left off. It tells the story of male friendship, following the experiences of up and coming actor Vince Chase and his 'entourage' of buddies, who have also made the move from New York to LA.
They are quickly immersed in the world of flash cars, hot girls and big money. Real-life cameos are also plentiful, with the likes Jessica Alba, Scarlett Johansson and James Cameron making appearances.
"It's a fantastic coup for us to have the hottest show in the US right now coming to ITV2 this autumn. Entourage is perfect water cooler TV; every episode of the comedy drama lets UK viewers take a peek inside the real lives of the Hollywood elite," said Zai Bennett, controller of ITV2. "Entourage helps cement our commitment to showing the hottest new shows around."[...] '
I was told about the show by none other than Kevin Smith who was talking about his mention in season 2.
