Many things are certain in "Twin Peaks" -- the murders are mysterious, the coffee is good and both the police force and the FBI love their donuts.

In this new official "Twin Peaks" teaser, posted today on YouTube, fans get glimpse of director and series co-creator David Lynch as he slowly eats a glazed donut in character as FBI Regional Bureau Chief Gordon Cole.

Lynch is reprising his role as the hard of hearing agent in the upcoming "Twin Peaks" revival series on Showtime next year. He's one of many original cast members making their return. (Editors' note: Showtime is owned by CBS, which also publishes CNET.)

The show originally ran for two seasons from 1990 to '91, receiving a Golden Globe for Best TV Series, and many Emmy nominations, during that time.

Kyle MacLachlan (Agent Cooper), Shelly Johnson (Madchen Amick), Michael Horse (Deputy Hawk), Bobby Briggs (Dana Ashbrook), Deputy Andy Brennan (Harry Goaz), James Hurley (James Marshall), David Duchovny (Denise/Dennis Bryson) and Doctor Jacoby (Russ Tamblyn), among others, are all part of the revival cast, as well as characters who previously died -- Ray Wise (Leland Palmer) and Walter Olkewicz (Jacques Renault) -- from the original series.

The "Twin Peaks" revival series debuts on Showtime in 2017.
