Thus, Primer picked the perfect tool for creating confusion. As Abe and Aaron, two young engineers, attempt to battle the forces of gravity, they accidentally crack the secret to time travel. The technological implications are interesting enough to them, but the financial (and other) opportunities available are a powerful draw as well.

As they test the machine, and struggle to figure out practical applications (they are engineers, after all), complications in the stream of time crop up that begin to work against them. The story is quite complicated, as the boys go back in time several times, a move that any fan of time travel stories can tell you is a guaranteed mistake. Ripples of time, or paradoxes, are powerful forces, which are not to be trifled with, as they never can be undone easily.

While focusing on such a sci-fi/fantasy idea could have sucked the connection the audience feels right out of the film (as happens so often in this genre), the story doesn't ignore the characters' humanity, which is truthfully the story's motivation. Ideas of greed, love, loneliness and trust are front and center, acting as the fuel in the film's engine. This is no fanboy geek-out. It's as thought-out a human drama as we have seen in recent time, wrapped in the mind-twisting concepts of time travel.

Shane Carruth, a former engineer, wrote, directed, edited, scored and starred in the film, giving it the kind of singular vision it needed to succeed at this kind of storytelling. The majority of the cast worked as crew as well, helping to solidify the all-for-one feel. Shooting the film on no real budget, he was still able to create a good looking film, one hindered only by the most concrete of details (stock, camera, lighting, etc.) His innate sense of style and ability with the computerized aspects of filmmaking, combined with truly imaginative creativity to make a film that tells an engrossing and entertaining story that doesn't go for the easy answer. This is the definition of great independent filmmaking.

The DVD
New Line is releasing Primer on one DVD, in a standard keepcase. The anamorphic widescreen menus are all animated, with extensive transitions, sporting an industrial casing theme that doesn't quite fit with the low-budget look of the movie. Options available include Play, Audio Set-Up, Scene Selections and Special Features. The audio options are English and Spanish subtitles, while the scene selection menu features video previews and titles for each scene.

The Quality
Primer was shot in a very low-budget style, which means Super 16mm film, natural light and a lot of grain. The movie doesn't look polished, especially during darker scenes. Depending on your tastes, this can be very frustrating or no big deal. The film is presented in anamorphic widescreen, and has just a minor amount of dirt and damage; which isn't half bad considering the budget.

The audio, a Dolby 2.0 track, is troublesome, in that the sound isn't consistent, and some dialogue is simply inaudible. The director has admitted to being bad with sound, and he isn't kidding. It is advisable to keep the subtitles on throughout the film. The sound effects are good, as is the music, which help build the film's atmosphere, so there's some good in the audio.

The Extras
There are only two main extras on this release, but they are both deep in terms of content. Two feature-length audio commentaries are included, one from Carruth and one with Carruth and members of his cast and crew. The tracks follow the standard multi-track style of commentary, as the solo focuses on the actual production of the film, talking about how scenes were shot and the writing of the story. There are some unanswered questions from the film addressed in this track, but for the most part, this is a filmmaker's theory and practice commentary. Carruth keeps things moving and doesn't get bogged down by the details, displaying a sense of humor.

The second track is more fun, featuring Carruth, actor/cinematographer Anand Upadhyaya, soundman Reggie Evans, actor/PA David Sullivan, actor/caterer Chip Carruth and camera operator Danny Bueche. This is more of a reunion/remembrance track, but there's still a good amount of info about the film, even if some of it is repeated from Carruth's track. Also found on this disc is Primer's trailer, which was spectacular in terms of mood and in building interest in the film, along with several other New Line previews.
