Fall 2021 is heating up as geek showbiz news continues to flow in, and it's time for a round-up!

Disney+ announced a release date for the long-awaited Book of Boba Fett series: The Mandalorian spinoff will start streaming on December 29.  The release of this series will give the IP renewed visibility, and may have a significant impact on certain collectible Star Wars comics starring the infamous intergalactic bounty hunter (see "'Star Wars' Collectible Comic Prices" and also, "Five Hidden Gems").

Dark Horse Entertainment chose Alice Waddington, director of Paradise Hills, to helm the adaptation of Dept. H, according to Deadline.  This adaptation is based on the comics created by Matt and Sharlene Kindt (see "TPB Planned").  T.S. Nowlin (The Maze Runner) has been tapped to write the script, and Mike Richardson, Keith Goldberg and Paul Schwake from Dark Horse Entertainment will produce.

A reboot of Babylon 5 is in the works at The CW, according to Variety.  The original Babylon 5 series ran for five seasons with 110 episodes and seven TV movies (see "'Babylon 5' Film Reboot").  The new series will be a "ground-up" reboot, with Babylon 5 creator J. Michael Straczynski onboard to write and as executive producer.

Warner Bros. DC has added new cast members to Aquaman and the Lost Kingdom, according to The Hollywood Reporter.  Jani Zhao, Indya Moore and Vincent Regan have joined director James Wan and Jason Momoa in this movie that is already in production. This movie is scheduled for release on December 16, 2022 (see "Best in Shows -- 2022").

Netflix released a teaser for Super Crooks (see video below).  The anime will release on November 26, and be followed by a live-action adaptation of Super Crooks at a later date (see "'Jupiter's Legacy' Ends").

Disney+ put out an official trailer for Muppets Haunted Mansion, which is an Original Special that will release on October 8.  The special stars Taraji P. Henson, Will Arnett, and Yvette Nicole Brown alongside the Muppet characters as they take on roles of the ghosts and haunts found in Disneyland's Haunted Mansion attraction.
