Broken Lizard made the 2001 police comedy and on Tuesday asked for $2 million in contributions to get "Super Troopers 2" produced.
Broken Lizard says Fox Searchlight has agreed to distribute the sequel in North America if the comedy troupe can fund the making of it.
The call for contributions was posted on Indiegogo.com and had raised about $500,000 by Tuesday afternoon. The campaign runs for a month. If the goal is met, shooting will start this summer.
The campaign mirrors that of the "Veronica Mars" film Warner Bros. released last year after a Kickstarter campaign.
"Super Troopers" is about five Vermont state police troopers. It made $23.2 million worldwide.
