Extras. There is a nice complement of bonus material.

• First off, both versions of Razor are included. The broadcast version, running about 87 minutes, and the unrated version, running about 103 minutes.
• Commentary. This full length track features producer Ronald D. Moore and writer Michael Taylor. It is a very good track with very little in the way of dead air. They offer up compliments and criticism to their baby in equal measure, as well as giving some background information on the series and the shooting of this movie.
• Deleted Scenes. Three cut scenes. The first is a young Lee Adama awaiting transport to his first ship. The second features a brief scene between Kendra and Kara. The third has Lee and Kara reviewing footage of a civilian ship they shot down. (3.5 minutes)
• The Look of Battlestar Galactica. This is an interesting, if all too brief, look into how they went about deciding and designing how the show would appear. It goes into how they wanted to step away from the standard science fiction look and make it more familiar. (8 minutes)
• My Favorite Episode So Far. This features interview clips with cast and crew concerning their favorite episodes and scenes. It is nice to get a glimpse of what the actors like best, and where they feel everything fell into place. (10 minutes)
• Season 4 Sneak Peek. Don't watch this until you have watched the movie. It is a teaser of what could be happening in the last season, and how Razor plays into that. (2.5 minutes)
• Season 4 Trailer. A brief collection of clips from next season. (>1 minute)
• Minisodes. These are the shorts that ran on the Sci Fi Channel to promote the movie, as well as appearing online. These are a perfect example of what the strike is about. They are also good character bits. Some of these were reintegrated into the unrated version, but not all of them. (19 minutes)

Bottom line. Not important in the long run, but still a great watch. There are lots of character bits to flesh out known characters, humanize deceased ones, and introduce new ones. It fills in continuity holes. Most importantly, it is highly entertaining, has some great acting and delivers some strong action. I absolutely cannot wait until the next season begins!

I did find this wiki, which offers much information (spoilers!) about the film that is worth checking into.

Highly Recommended.
