The Big Bang Theory: Season One and Two
($29.98 DVD, $39.99 Blu-ray; Warner Home Video)
The first two seasons of this geeky sitcom series about four physicist pals—including out Emmy winner Jim Parsons—get the Blu-ray treatment. While both DVD and Blu-ray editions boast behind-the-scenes extras, the latter offers an exclusive gag reel.
