That is fairly old - 1994 - Gary Sinise (from CSI NY fame) was the lead and he looks very young in it; only a couple of years older than I am now.

I saw an interview with Corin where he said he had to work really hard to put on the muscle for working on Stargate. I should get the disc out with him on in CSI:NY and have a look to see how thin he is on that.

I am also thinking he got the part in CSI because he had worked with Sinise before.
