In late 2002, Nintendo was giving out a free preview DVD highlighting upcoming games for both the Gamecube and the GBA. The DVD could also be browsed on a computer to access additional content. Metroid Prime was the lead game for that disk, and there were lots of goodies for it - which have been reproduced below.

For reference, Prime's coding was finished by October 29th and it was released on November 18th (for the original NA = 0-00 version).

Both the NA and European release of Metroid Prime had a demo game on the space frigate preceding them.

You can download a quick run of the NA demo (and get higher quality versions of some of the trailers above) here: Link to FileShack
The file called "All Demo Footage" contains lower quality encodes of "Demo Intro" and "Demo Footage" 1-7.
