This summer has introduced a few serious contenders for the worst movie ever in the toy-inspired Bratz and Lindsey Lohans I Know Who Killed Me. Only time will tell if these upstarts have what it takes to join the ranks of the best of the worst. The best worst films, such as Manos: Hands Of Fate, Showgirls or Plan 9 from Outer Space, are immensely entertaining in their relentless atrociousness, while just plain bad movies are guilty of being boring and deserve to be forgotten. No one can accuse Troll 2 of being boring. Filmed in Utah by Italian director Claudio Fragasso (working under the pseudonym Drake Floyd), Troll 2 is connected to the original Troll in name only. In a post-modern stroke, it features not a single troll, but rather vegetarian goblins (represented by little people in potato sacks and rubber masks) who inhabit the town of Nilbog (spell it backward). Brimming with rotten acting, illogical plot twists and incomparable one-liners (I have to release my lowest instincts with a woman.), Troll 2 proved its mettle by sitting atop the Internet Movie Databases charts as the number-one lowest-rated movie for years. This Friday, August 24, at midnight, the Tivoli Theatre (6350 Delmar Boulevard, University City; 314-995-6270) hosts a special screening of Troll 2 attended by cast members Michael Stephenson (Joshua) and George Hardy (Michael). Stephenson and Hardy will field audience questions and compile footage for the documentary Best Worst Movie, which will celebrate and perhaps explain the films devoted cult following. Troll 2 also plays at midnight on Saturday and 10 p.m. Sunday (August 25 and 26), but without the presence of Stephenson and Hardy. Tickets are $6.50 for all shows.
