SPOILERS: Dexter Season 6 Secrets Revealed

Though Season 5 of Showtimes flagship show, Dexter, had its critics, fans can't wait for the DVD release of the most recent season featuring America's favorite serial killer, and now they don't have to. As Showtime gears up for a killer Season 6 premiere, fans are rushing to their local DVD stores to catch up on Season 5, which just went on sale today on DVD and Blu-ray.

If you're among the dwindling population who didn't catch last season, starring Michael C. Hall as Dexter and guest starring silver-screen star Julia Stiles, you'll be pleased to know that you have time to soak up the latest installments, watching them with marathon-like intensity if you please. The Blu-ray box set features over ten hours of bonus features, available for the first time through BD-Live, a system that allows you to download features from the internet and enjoy interactive content via your Blu-ray player.

The good-ol' fashioned DVD also allows access to most of the footage, which includes a host of cast interviews, including Hall, Stiles, and Hall's ex-wife Jennifer Carpenter, who plays Debra on the show. Carpenter and Hall filed for divorce in December 2010 after revealing that they had already been separated for some time, but they still appear on the show alongside each other as brother and sister.

In the meantime, Dexter producer Scott Buck is letting a few cats out of the bag on what fans can expect for Season 6, not the least of which is his assurance that Dexter will return to its "creative foundations." When we next encounter him, he will be one year in the future, having had time to clear his head after the death of his wife Rita (played by Julie Benz) at the end of Season 4, not to mention his brief jaunt with Stiles' character, Lumen in Season 5. "We thought a clean start to this season would be to jump ahead a year, so he's not getting over Lumen, and he's not still in the throes of dealing with the Rita thing," producer Sarah Colleton told TV Guide. "We wanted to jump ahead a year and find that Dexter has gotten his groove back. He's gotten over Rita and Lumen." What results is a Mr. Morgan who "still wants to play" even after all these years.

In addition to promising what everyone wants to see — a revitalized, "strong and focused" Dex — the show is offering some big names on its Season 6 roster. Battlestar Gallactica's (2000s) Edward James Olmos will come on board as the dangerously charasmatic Professor Gellar, and Colin Hanks will appeaer as Travis Marshall, a friend who is under the new villain's thrall. Mos Def will play a born-again strreet thug who tries to lead his fellow man on a righteous path.

While it remains doubtful that Dexter will take that path, bringing his "dark passenger" along, he's sure to have a few tricks up his sleeve. In the meantime, fans have over a month to get caught up and prepared for what lies ahead.
