I watched every episode of the show that I could after that, and while Tate’s hot body continued to excite, I never again saw him shirtless. Also, he seemed to stop being blond after the first season, his hair becoming more of a reddish brown as he presumably spent less time on Australian beaches, and he seemed to gain a little weight, becoming a little stockier (but hardly less sexy).
I occasionally saw Tate in other shows and movies after that (including A Cry in the Dark and as recently as a guest spot on Lost), and heard that he showed up wearing nothing but short shorts in an Australian thriller called Summerfield. Curious, I bought the Summerfield DVD online and converted it to NTSC and was very glad I did. While Tate was a little chunkier than during Space:1999, the flick showcased his great body. There was even a nude scene, although his crotch is artfully concealed throughout. But as tight and revealing as his shorts were, you got a pretty good idea of the size and shape of his equipment anyway. On top of that, the flick is a good atmospheric thriller.
