The standard season box sets of Stargate: SG-1 were each loaded with special features. And they're all included with the ten season box set, with a few additonal features not found in the single season sets.

Director's Series - These are short films--running about ten minutes or more--which feature a director talking about a specific episode that he's working on at that time. They're shot with a hand-held camcorder, and usually have a very intimate feel to them. All of the Director's Series are recommended, thanks to the inside look they offer at the production of the series, but the Directors Series segments with Martin Wood and Peter Deluise are especially good, since both Wood and Deluise (the son of comic actor Dom Deluise) are pretty funny.

The "Profile On" series - each of these segments looks at each of the characters in the Stargate universe, focusing on O'Neill, Carter, Jackson, Teal'c, and so on.

Video Diary - these segments are the result of camcorders being given to the cast. Each cast member has their own Video Dairy, where they show what goes on over the course of a day on the Stargate set. Fun to watch, as they often capture the behind the scenes humor.

Stargate: SG-1: The Lowdown ~ From Stargate To Atlantis The Lowdown ~ Behind The Stargate: Secrets Revealed - Originally produced for the Sci-Fi Channel, these documentaries are still extremely enjoyable to watch, especially for diehard fans of the series. Watch for a very funny outtake featuring Amanda Tapping and Richard Dean Anderson from the episode "Solitudes" in the first Lowdown documentary.

SciFi Inside: SG-1's 200th Episode - A detailed, behind the scenes look at the 200th episode of Stargate SG-1, which aired in its tenth season.

Behind the Mythology Of SG-1 - Christopher Judge and Michael Shanks are your hosts for this look at the detailed backstory that was created by the SG-1 writers.

Stargate: SG-1 True Science - Amanda Tapping is your host for this sicentific look at the real-life technology and science behind someof the ideas from the series. A fun look at basic science. But beware the section that looks at real-world parasites; it gets icky.

The Commentaries - the majority of the episodes come equipped with commentaries, and many of these feature the cast and are a lot of fun to listen to.
