It rained so much during filming of The Tripper that director David Arquette, at the wrap party, gave each cast and crew member a personalized poncho. In fact, one of the few days it DIDN'T rain was when they shot the rain scenes. They had to make rain for these scenes.
When David Arquette did a panel for this film at the 2006 San Diego Comic-Con International, the footage he wanted to show was missing. He offered a reward of a car that was used in the movie for the return of the footage.
The film was originally going to be a part of After Dark Production's "8 Films to Die For," but Arquette wanted the film to be released in theaters and on April 20th (4/20), so they respectfully parted ways.
One of the production managers discovered a very real human finger on the ground during filming. The crew eerily theorized that it was connected to the multiple real-life serial killers that allegedly operated in those very woods.
David Arquette stated during his bus tour that he came up with the idea for the film during a Reggae party held outside, where he envisioned a murderer "coming out of the woods and slashing up all the hippies." The idea eventually led to The Tripper.
The excrement smeared on Paul Reubens was made with cocoa, chunky peanut butter and corn. In the DVD extras, Thomas Jane walks by and quips "You look like shit, Paul." When it first was applied Paul quipped "I feel like shit." When Jacob Olthof wore the suit as his stunt double he thought he smelled great.
