Here are RottenTomatoes.com's "Tomatometer" ratings of movies I've had speaking parts in. Hmm... I sense a pattern here.

Movie	Year of  Release	Tomatometer Rating	Fresh or Rotten
Hollow Man	2000	26%	Rotten
Girl, Interrupted	1999	52%	Rotten
Shadow Conspiracy	1996	0%	Rotten

A Tomatometer ranking of 25% means 25% of the reviews were basically positive and 75% were negative.  A rating of at least 60% is required for a "Fresh" tomato rating.

Note that Shadow Conspiracy has a T-meter rating of 0%.  This is really quite a dubious achievement. Even Gigli eked out 7%.
