Florida’s biggest comic book and entertainment convention — MegaCon Orlando, set for March 30 — announced its first guests Wednesday.

This week’s new entertainment releases include a new album from Arcade Fire, a documentary about Sheryl Crow that's described as an “intimate story of song and sacrifice” and a four-part documentary about the Three Mile Island nuclear disaster.

It's betting that consumers are willing to add yet another paid streaming service in an increasingly crowded field. “Paramount+ has a mountain of challenges ahead of it," said Tim Hanlon, CEO of Vertere Group, playing off the Paramount+ tagline, “A mountain of entertainment." CBS All Access, Showtime and BET+ now have nearly 30 million subscribers, some of who will shift to Paramount+. ViacomCBS said some of the studio’s films, including “Mission: Impossible 7” and “A Quiet Place Part II,” will go to its fledgling streaming service, Paramount+, after 45 days in theaters. “If they want to act like a second tier streaming service, they're doing a fantastic job."
