Bryan Fuller is on a roll. Although his Munsters reboot Mockingbird Lane didn't find a home on NBC, the Pushing Daisies creator developed a hit with Hannibal. That success led to the announcement of his The Lotus Caves adaptation for Syfy, now called High Moon. John Christopher's novel depicts a future where each Earth's countries has a mining colony on the moon. Things get a little hairy when alien lifeforms reveal themselves.

According to The Hollywood Reporter, Chris Diamantopoulos (The Office, 24) and Jake Sandvig (Easy A) have joined the cast. Here's how THR described the two characters:

Diamantopoulos will play Ian, a chief investigator for the American federal government who has been dispatched to the moon to figure out the cause of an explosion. He's stunned by what he discovers. The character is outwardly the strong and silent type but has a dizzying agenda that helps make him a closeted neurotic. The only person who can access that side of him is his brother, Marty (Sandvig), whose ability to get under his skin has led to a complex and antagonistic relationship.

Sandvig's Marty is a convict sentenced to serve time as a laborer on the moon. Passionate about his job, Marty is investigated for espionage and sabotage when a giant blast goes off near an area where he was working. The character finds something he knows is a game-changer and will go to the end of the moon to prove he's telling the truth about its existence.

The series will kick off with a 90-minute pilot that starts shooting on Aug. 26 in Canada. Fuller co-created the original story with Jim Danger Gray (Hannibal, Pushing Daisies), who wrote the script for Adam Kane (Falling Skies, Being Human) to direct.
