The latest geek TV update has all sorts of reveals, from casting, to new images, to new series.

The FX adaptation of Brian K. Vaughan and Pia Guerra’s Y: The Last Man has landed a solid cast that includes Oscar nominee Diane Lane (Under the Tuscan Sun), Barry Keoghan (Dunkirk), Imogen Poots (Green Room), Lashana Lynch (Captain Marvel), Juliana Canfield (Succession), and Marin Ireland (Sneaky Pete) according to The Hollywood Reporter. Keoghan will play the last man, Yorick Brown, and Poots will play Yorick’s sister Hero Brown. Lane stars as family matriarch Senator Jennifer Brown. Lynch is playing the formidable Agent 355, Canfield is portraying love interest Beth, and Ireland is presidential assistant Nora. The series is based on the 60-issue comic series by Vaughan and Guerra that was published by Vertigo. In the comic, Yorick and his pet monkey Ampersand were the only survivors of a sudden plague that wiped out any mammal possessing a male chromosome (see “FX Greenlights 'Y: The Last Man'”).

The head writer of the immensely popular Avatar: The Last Airbender series, Aaron Ehasz, has a new animation project with Netflix. The streaming giant revealed the poster and basic plot of The Dragon Prince via Twitter, describing the show as a “series about two human princes who forge an unlikely bond with the elfin assassin sent to kill them,” all of whom begin a quest to bring peace. The kid-friendly series is expected to air later this year.

Speaking of Netflix and Twitter reveals, the first poster for The Chilling Adventures of Sabrina was also unveiled via tweet, this time from series creator Roberto Aguirre Sacasa. Kiernan Shipka is playing the lead, with Miranda Otto in the role of Aunt Zelda (see “'The Walking Dead' Ratings Slip, Hot Trailer for 'Fahrenheit 451,' Animated 'Rocketeer' and 'Moon Girl,' 'Sabrina' and 'Titans' Casting”). Lucy Davis (Etta in Wonder Woman) is playing Aunt Hilda. Netlfix ordered 20 hour-long episodes for two seasons of the series about the teenaged half-human, half-witch (see “Sabrina the Teenage Witch's Chilling Adventures Move To Netflix”).  

HBO’s Game of Thrones prequel is set to begin shooting in Belfast, Ireland, in October according to the Belfast Telegraph. The area also serves as a shooting location for the original Game of Thrones series, Syfy’s Krypton, and the Obi-Wan Kenobi Star Wars spinoff, which begins shooting in April 2019 (see “Another 'Star Wars' Spinoff”). The Game of Thrones prequel, which has a working title of The Long Night, is set 1,000 years before the events of A Song of Ice and Fire (see “HBO Orders Pilot for First 'Game Of Thrones' Spinoff”).

Alongside the recent official announcement of the DC Universe over-the-top streaming service (see “Warner Brothers Entertainment Reveals 'Dc Universe'”) came a pair of new images featuring Brenton Thwaites as Dick Grayson/Robin in Titans. Decidedly more beat up in the new images than he was in a photo released late last year (see “First Look At Robin's Costume”), the images offer the first full-length look at the dark and tactical costume. The gritty live-action take on Teen Titans also includes Rachel Roth/Raven, Starfire, and Beast Boy (see “Misty Knight's Bionic Arm; 'Heartthrob' Optioned; 'Locke and Key,' 'Titans,' 'Quantum and Woody' Casting”). Hawk and Dove will also appear on the show (see “'The Greatest American Hero,' 'The Boys,' 'Game of Thrones' Piracy, 'Titans' Casting”). A release date for Titans hasn’t been announced, but it recently wrapped filming. DC Universe is set to beta test in August and launch in fall. 

Jon Bernthal is coming back from the dead (again) for Season 9 of The Walking Dead, reports Variety. Bernthal’s character Shane died (twice) in the Season 2 finale, and appeared as a ghost in Season 3, but the nature of his appearance in the upcoming season remains to be seen. Bernthal has kept busy in the interim, starring in Netflix’s well-received Punisher series (see “New Trailer For 'Marvel's The Punisher'”). Whatever AMC and the showrunners decide, Season 9 is set to diverge entirely from the comics because major stars Andrew Lincoln (Rick) and Lauren Cohan (Maggie) are leaving the series (see “AMC's 'Walking Dead' Story Diverging Wildly From Comics”).
