6. Showgirls (1995)
The $45m produced movie has some of the worst acting ever seen on the big screen, mostly thanks to Saved By The Bell alumnus Elizabeth Berkley, who climbs the Las Vegas fame ladder and shows how to relieve tension by violently splattering ketchup on your French fries. Berkleys Nomi seems to always be in the right place at the right time as her roommate happens to know the over sparkly Crystal Conners, as if conventionally complex story-telling was beyond the script. The ungratifyingly awful pool sex scene with Lynch favourite Kyle Maclachlan is almost as unsexy as the french kissing scenes with Gina Gershon, and inspired some of the biggest laughs of any non-spoofing sexy film. Yes, Berkley managed to flip the lid on her good girl image but in the end, Showgirls became the funniest homage to the camp white trash Vegas, or as the late Roger Ebert described it a perfectly good waste of a NC-17.
