Discovery is seeking $3 million in damages after two stars of "Deadliest Catch," Jonathan and Andy Hillstrand, allegedly failed to live up to an agreement to complete a spin-off project.

According to the breach-of-contract lawsuit, filed last week in Maryland Circuit Court, the Hillstrands were to film a one-time special called "Hillstranded." The duo was coming off five seasons of "Deadliest Catch," one of the most popular programs on any Discovery-affiliated network. The special was to document the team's various adventures in Alaska; work unrelated to their jobs as crab fisherman. Two weeks of principal photography was shot in June, but there was still work to do.

"The Hillstrand Defendants determined that they would reverse course, dishonor their promises, and refuse to render the services necessary to complete 'Hillstranded,'" reads the complaint.
