This Is Us unveils Season 4 trailer, gets an extended premiere, adds M. Night Shyamalan and 9 more

NBC says the Sept. 24 Season 4 premiere will be an extended event, starting at 9 p.m. and ending "shortly after 10 p.m." This Is Us also released a Season 4 trailer showcasing ten new additions to the cast, including When They See Us' Asante Blackk and Marsha Stephanie Blake, Omar Epps, Bahara Golestani, Jennifer Morrison, Timothy Omundson, director M. Night Shyamalan, Julian Silva, Auden Thornton and Nick Wechsler. Shyamalan's involvement as an actor on This Is Us is a "shocking twist from the master of shocking twists," says Sam Barsanti. "It’s freakin’ M. Night Shyamalan!" he says. "Talk about a twist! We don’t know what he’ll be doing on This Is Us, but if his other acting roles are anything to go by, he’ll be distractingly crucial to the central plot. Maybe he’s the inventor of the slow cooker that killed Milo Ventimiglia?"
