Dispatches: Weekly TV news The CW is a triple threat in December when it takes the crossover to new heights. A three-night, three-show event featuring characters from “Arrow,” “The Flash,” and “Supergirl,” will introduce Lois Lane, among other new additions. The fun begins with an episode of “The Flash” on Dec. 9 at 8 p.m. Winter may be coming to Amazon as the retail giant’s streaming arm adds “Game of Thrones” writer Bryan Cogman to its impressive list of producers.

In a video posted to his Team Coco YouTube channel, he announced that his complete late-night archive will become available online through a new website set to launch in January. Contenders: Buzz worthy shows worth your time Liberty City, Miami, has the distinction of being the birthplace of an unusually high number of elite football players. “Warriors of Liberty City” (Starz) looks at the young gridiron stars who hope to join their ranks. It’s the promise of the American Dream as realized through sport and a compelling look at the challenges and triumphs these children and their families face on and off the field. Netflix’s intriguing drama “Maniac,” starring Emma Stone and Jonah Hill, premieres Sept. 21. The premise of a drug trial that promises to cure all sickness of the mind, including heartbreak, plus the breakout talent of Julia Garner (“Ozark”) should make for a binge-worthy weekend. The remake of “Magnum P.I.” (CBS, 9 p.m.), along with mysterious airplane drama “Manifest” (NBC, 10 p.m.), both premiere Sept. 24. “Manifest,” which poses interesting questions about grief, fate and purpose has more to offer than the fast cars and scenic landscapes of the Hawaii-based investigator.
