(In theaters, May 1999) That wacky Canadian Cronenberg strikes again with an average “What is Reality?” tale made more memorable by the use of biological “technology” and some scenes rather suggestive of anal sex. No, really. Two actresses shine, what with Jennifer Jason Leigh (As a champ game designer with a lovely hairdo! In a tight blue miniskirt!) and Sarah “Raaah!” Polley. While rather slow in its first hour, Existenz picks up and ends with a really enjoyable last five minutes. Some may be disappointed with its The Usual Suspects-type ending, but I came out of the theatre with a big goofy grin on my face, and any movie that manages that can’t be half-bad.
