To celebrate the impending release of the sixth season of The Big Bang Theory on DVD and Blu-Ray, as well as the Complete Seasons 1-6 boxset on both formats, we are giving two lucky readers the chance to each win a copy of The Big Bang Theory Complete 1-6 DVD Boxset. Multi-award winning programme creators Chuck Lorre and Bill Prady return for the sixth season, which introduces a new character to the mix. Kevin Saussman ("Ugly Betty") plays Stuart Bloom, the owner of The Comic Centre of Pasadena. He stars alongside Johnny Galecki ("Rosanne"), Kaley Cuoco ("8 Simple Rules"), Jim Parsons ("Judging Amy"), Kunal Nayyar ("NCIS"), and Simon Helberg ("Reno 911") with Mayim Hoya Bialik ("Blossom") and Melissa Rauch ("Dirty Sexy Money"). In The Big Bang Theory: The Complete Sixth Season, fun discoveries multiply. Leonard learns that jealousy is bad for a relationship (with Penny) but science is good for seduction (of Penny). Howard finds life in the International Space Station is no escape from terrestrial turmoil between his mom and his new wife Bernadette. Raj meets someone special who may be a good match, if he can keep her from fleeing mid-date. And then there's Sheldon. He learns what not to say after facing harassment charges or competing for tenure at work and how Dungeons & Dragons can be the icebreaker his relationship with Amy needs. The new Season 6 package contains all new Extra Features, including featurettes and a gag reel, and a guest appearance by Buzz Aldrin. The Big Bang Theory Season 6 and Complete 1-6 Boxset are available to buy from 2nd September on DVD and blu-ray.
