There have been happenings on several geek-related television properties recently and we round them up here.

The Walking Dead co-creator Frank Darabont filed a lawsuit against AMC over his share of the zombie show’s profits in 2013 (see “Showrunner Sues Over 'Walking Dead'”). The two sides have completed the discovery process (see “Darabont Wins Motions in 'Walking Dead' Lawsuit”), and now the plaintiffs have filed a certificate of trial readiness seeking a damages verdict in excess of $280 million, according to THR. “Plaintiffs' damages claim has no basis in reality and we will continue to vigorously defend against this lawsuit,” AMC told THR. The judge, Justice Eileen Bransten, held a status conference this week and warned both sides that if the case is allowed to move forward, it will have to go to trial, and her 2017 schedule is already booked. The soonest the trial can be scheduled is 2018.  Season 7 of The Walking Dead premieres on October 23.

Amazon is developing a limited drama series based on G. Wayne Miller’s non-fiction book Toy Wars: The Epic Struggle Between G.I. Joe, Barbie, and the Companies that Make Them. The book chronicles the real-life battle between toy giants Hasbro and Mattel in the 1980s and 1990s. According to Deadline, Josh Gad (Angry Birds) will co-write and star, Josh Schwartz will co-write and showrun, Ryan Dixon will co-write, and Seth Gordon will direct the project.

The movie adaptation of Stephen King’s The Dark Tower is already set (see “End of February Geek Movie Round-Up”),and now sources at the production company MRC have revealed the plans for the companion TV series to EW. The show is being financed by MRC and Sony Pictures, who have already committed to a pilot and 10-13 episodes. The Dark Tower show will begin shooting in 2017. Star Idris Elba, who plays older Roland in the film, will appear in the show, as will Tom Taylor, who plays Jake Chambers. The show will focus on the fourth book in the saga, Wizard and Glass.
