Topic: Was reading a 1998 Starlog interview...
...with O'Connell. (http://sliders.net/articles/starlog252.html)
Interesting tidbit at the end:
"Likewise, two Sliders alumni may slide again. According to O'Connell, Rhys-Davies has tentatively agreed to return for a few episodes. And Lloyd hasn't ruled out the possibility of re-appearing this season either. "That's the neat thing about Sliders. Nothing is definite or for sure. Just because something happened in one universe does not mean it's that way elsewhere. Anything is possible in this show, and for me that's really neat," O'Connell explains."
Can anyone shed light into what happened here? Was the interviewer just embellishing? Did it all come down to lack of money and/or certain people involved? Probably.
But seeing as this interview took place half-way into season 4, I'd assume Sabrina and John understood what the situation was.
Maybe it was just O'Connell saying things to get fans hopes up at the time for bigger numbers.
