Since You've Been Gone (1998)

Seen on 15-7-2009 - HBO
The whole film is set on class reunion of middle-aging men and women who have left school ten years ago and have now by and large settled in life. It's a brilliant mise en scene portraying in a comedic genre their pretended successes, their actual frustrations, their vengeful pranks on those they had grudge in school, etc. Lara Flynn Boyle who stars as a wild jokester is in her mischievous best with her acts of annoyance sticking chewing gum in a woman's hair, short-circuiting power and blowing up the audio speakers, raising false alarm through an anonymous call, spilling wine on a woman's clothes, etc. These border on slapstic, but are meant to be funny, I suppose. One also wonders if people are like this in a class reunion!
