Executive Producer Reveals Lost Guest Star on Twitter

In the months leading up to each of Lost's previous season premieres, executive producers Damon Lindelof and Carlton Cuse have generally kept mum about all things pertaining to the show. Heading into their final season, the producers are taking a different approach to revealing Lost news.

Late on Tuesday, Cuse tweeted a clue for Lost fans to figure out. "Damon and I are die hard fans of this impeckable actor who keeps the barr high and just signed to guest star on the show. Life is good!"

The misspellings were clues leading to the name...William Atherton.

In order of the clues: Atherton was in both Die Hard and Die Hard 2, his character's name in Ghost Busters was Walter Peck, on Desperate Housewives he played Dr. Barr and the 62-year-old actor was also Charlie Crews' nemesis on Life.
