Trial and Error is a 1997 American comedy film directed by Jonathan Lynn and starring Michael Richards, Jeff Daniels, and Charlize Theron.

His boss and future father-in-law sends him to Paradise Bluff, Nevada, to request a continuance in a mail fraud case involving a cousin-in-law who is likely to be found guilty.

After Charlie drives from California to Paradise Bluff, he is unexpectedly greeted by his best man, actor Richard Rietti, who is determined to show his friend a great time prior to his wedding.

Despite Richards' popularity on Seinfeld, and Daniels' success as a comic actor in Dumb and Dumber, Trial and Error was a box office disappointment and earned mixed critical reviews.

Ebert thought the film was reminiscent of Billy Wilder's understated comedies, which "got a lot of the laughs by playing scenes straight" rather than going for obvious comedic gags.
