The Oscar party of the year was Miramax‘s pre-awards dinner March 22 at the Regent Beverly Wilshire. It’s become an annual tradition: actor nominees from one Miramax movie parody nominees from other Miramax productions.

This year, Robin Williams donned a rhinestone tiara to play Judi Dench in a scene from “Mrs. Brown”; Dench and Helena Bonham Carter did that wonderfully overwritten scene from “Good Will Hunting,” wherein Ben Affleck tells Matt Damon he doesn’t want to see him in the same place “20 years from now”; and Ben and Matt returned the compliment by doing a scene from “The Wings of the Dove”.

Affleck appeared in drag to get into his Bonham Carter role and borrowed Madonna’s cape for the scene. In her usual snarky mood, the Big M started grousing loudly when Affleck forgot and left her cape on the stage.

Oh, and what else happened? Matt Damon was all over current-girlfriend Winona Ryder, and ex-girlfriend Minnie Driver (his co-star in “Good Will Hunting”) was an obvious no-show. Smart girl.
