Worst Performances: Dumb and Dumber (1994), Down Periscope (1996), Turbulence (1997)

Sexy ginger Lauren Holly will always hold a special place in the hearts of moron-comedy fans, thanks to her love interest role in the funny movie classic Dumb and Dumber. Outside of her time romancing an idiotic Jim Carrey, though, Holly hasn't done much to stay on male (or female, for that matter) viewers' good sides. More ho-hum than full-on bad, she's the kind of attractive actress who initially catches one's attention but, minutes later, loses all command and fades into the background.
