I was watching the idiotic “Bio-Dome” (1996), and I was worried. Idiot Pauly Shore’s idiot girlfriend was being played by an idiot Renee Zellweger. Or so it appeared. I tried to do the math. “Jerry Maguire” came out around the same time. Could she have filmed “Bio-Dome” when she was a nobody, and it was just released later? Soon, the credits rolled. It turns out idiot girlfriend was played by Joey Lauren Adams, who is merely Renee Zellweger’s idiot twin. Meanwhile, the movie, which involves science-related hijinks and idiot Stephen Baldwin, also stars the famed “dickless” from “Ghostbusters.” So there’s that.
