Tonight marks the series finale of ABC's 'Life on Mars.'

The show, an American version of a Brit series of the same name, stars Jason O'Mara, Harvey Keitel, Michael Imperioli and Gretchen Mol and developed a cult following despite only one season on the airwaves.

Unfortunately, there weren't enough fans to warrant a second installment. (Reminding us of that other recent short-lived '70s-set series 'Swingtown' -- oh, 1970s, why must all the good shows that depict your awesome polyester wardrobes, feathery hairstyles and outrageously outdated mores be killed off so quickly? We're not counting 'That '70s Show,' and we think you know why.)

But, ahem, AOL TV was granted an exclusive on set visit to 'LOM,' where we got our '70s fix, but good.

So what was life actually like on 'Mars'? Read through our post to see the highlights (and then shed a tear for the passing of this fine, fine show -- we're nostalgic already).
