Series 1 and 2 are both region 2, while series 3 and 4 are region 0.
Here are all 4 series worth of hilarity from the highly acclaimed comedy by Writer/Director Graham Linehan and Ash Atalla, the Producer of The Office. The short story is that in the dark and shabby basement, the company's IT Support Team - bitter slacker Roy (Chris O'Dowd), socially inept Moss (Richard Ayoade), and their new boss, computer illiterate Jen (Katherine Parkinson) - rule their own domain of professional irresponsibility, mega-nerd ecstasy, and random acts of personal insanity.
The BAFTA Award winning IT Crowd: Series 1-4 Boxset (DVD) from the pen of Graham Lineham (Father Ted, Black Books and the Fast Show), comes this sitcom based in the offices of Reynholm Industries and focuses on its very special IT department, located in the basement, well away from real people. The comedy centres on the super geeky Maurice Moss (Richard Ayoade), the terminal slacker Roy Trenneman (Chris O'Dowd), and the ambitious but IT challenged Jen Barber (Katherine Parkinson). Richard Ayoade and Katherine Parkinson both picked up BAFTAs for these roles in the 2014 BAFTA TV awards. Matt Berry plays Douglas, the very non-PC son of the eccentric business titan, Denholm Reynholm (Chris Morris) while Noel Fielding vamps it up splendidly as Richmond, the goth who lives in the cupboard.
