Amazon's Galaxy Quest TV revival is back on track.

Writer-actor-comedian Paul Scheer (The Disaster Artist) has been tapped to pen the script for the Paramount Television-produced series. Scheer takes over for the feature film's original scribe, Robert Gordon, who was on board to pen the script for the Amazon reboot.

The Amazon series is described as a new take on the cult movie that starred Tim Allen and the late Alan Rickman as well as Sigourney Weaver. It remains unclear if any of the original stars, such as Tony Shalhoub, Sam Rockwell, Daryl Mitchell and Enrico Colantoni, will return. The original 1999 movie centered on the cast of a canceled, beloved sci-fi show that was forced to reunite to save the planet after aliens believe their show was real.

Mark Johnson, who produced the movie, is still attached to exec produce via his Gran Via Productions banner partner, Melissa Bernstein. It's unclear if Galaxy Quest director Dean Parisot is still attached. Gordon will exec produce.

Plans for the Amazon series were put on hold after Rickman's death. "We were ready to sign up, and [then] Alan Rickman passed away and Tim Allen wasn't available — he ha[d] [Last Man Standing] — and everybody's schedule was all weird. It was going to shoot, like, right now. And how do you fill that void of Alan Rickman? That's a hard void to fill," Rockwell said in April 2016.

Rickman died of cancer in January 2016 at 69. Shortly after his co-star's death, Allen talked with The Hollywood Reporter about the revival: "Galaxy Quest is really close to being resurrected in a very creative way. It's closer than I can tell you, but I can't say more than that. The real kicker is that Alan now has to be left out. It's been a big shock on many levels."

For his part, Allen is now available for the Galaxy Quest project after ABC canceled Last Man Standing.

Scheer, repped by UTA and Schreck Rose, counts acting credits that include Wet Hot American Summer: Ten Years Later, Childrens Hospital, Veep and Fresh Off the Boat. On the writing side, his work includes NTSF:SD:SUV, Childrens Hospital and The League, among others.
