SyFy just snagged a very important member of the 90210 zip code: Jason Priestley will guest star in four episodes of Haven. He’ll also direct the Sept. 9 episode. Priestley will play Chris Weekly, a role that SyFy describes as “a handsome but anti-social marine biologist who is forced to deal with an affliction most would consider a blessing — everyone suddenly loves him and will do anything he wants. Only Audrey Parker (Emily Rose) seems unaffected by Weekly’s `charms.'”

The Beverly Hills, 90210 alum will appear in the Aug. 5, 12, 19 and Sept. 9 episodes.

Haven is based on Stephen King’s tome The Colorado Kid and is currently in production in Nova Scotia. It stars Eric Balfour as Duke Crocker.

Priestley is also set to play a Harley-riding con man in the next season of Psych.
