In case you missed it, here's the entire first episode of the US version of "Life On Mars".
(Actually, I was at work last week when this aired, and, even though it's on my DVR, I haven't had a chance to watch it yet, myself. That pesky "paying job" thing keeps interfering in all the important things I need to do...)
[UPDATE May 2009: Apparently ABC has changed the stream attached to this link. It no longer shows the entire first episode, but only the first eight minutes of the first episode. I personally changed nothing and have no control over the content, so any changes have been wrought on the other end. I guess if you want to see the whole thing, you'll just have to wait until the DVD comes out.]
