Riding motorcycles on ice at top speed sounds like something you would see on "Jackass," yet Xtreme International Ice Racing is coming to UMass. This Coca Cola-sponsored event will bring world champion motorcycle racers, such as Ed Hubbles (pictured), into our backyard. The racers ride side by side, reaching speeds of 60 miles per hour as they glide on top of the ice. Racers will compete on both two- and four-wheeled bikes. Local Amherst riders will also participate in small venue races. (Wed., 7 p.m., Mullins Center, UMass. Tickets $2-$15 at 733-2500 and www.ticketmaster.com.)

Who knew she could act? Yes, in "Monster," Charlize Theron proves that she is more than just another pretty face in Hollywood. In fact, according to about.com, her make-up artist Toni G deserves almost as much credit as Theron herself for making the actress look positively grotesque as Aileen Wuornos. The real Wuornos was a prostitute who earned the media designation of "the first female serial killer" after she murdered several of her "johns" during the 80s. She was executed in October of 2002 after 12 years on Florida's death row. Christina Ricci also turns in a strong supporting performance as Selby Wall, Wuornos' fellow misfit and lesbian partner. The movie is certainly disturbing, but never boring. It is absolutely worth seeing, although I don't know if I would have been comfortable seeing it in a theater-luckily, I managed to find a bootleg copy on DVD in Thailand.
