NBC ends the current TV season in solid position. The network canceled a few underperforming shows, but on the whole, has a dependable lineup of dramas and comedies.

Still, NBC does need to fill some holes this fall, and to do that, it's turning to veteran producers like Michael Schur ("The Office," "Parks and Recreation"), Eric Kripke ("Supernatural"), and of course, all-star Dick Wolf. The latter is contributing yet another installment in his Chicago series, "Chicago Justice."

Most of NBC's new series do not have trailers, including high-profile projects like a "Taken" TV adaptation and the "Wizard of Oz" reimagining "Emerald City."

Here are the network's three available trailers:

"The Good Place": From Michael Schur, executive producer of "Brooklyn Nine-Nine," "Parks and Recreation" and "The Office," comes a smart, unique new comedy that follows Eleanor Shellstrop (Kristen Bell, "House of Lies," "Veronica Mars"), an ordinary woman who, through an extraordinary string of events, enters the afterlife where she comes to realize that she hasn't been a very good person. With the help of her wise newfound afterlife mentor (Ted Danson, "Bored to Death," "Cheers"), she's determined to shed her old way of living and discover the awesome (or at least the pretty good) person within. Directed by Drew Goddard, the Oscar-nominated writer of "The Martian."

"This Is Us": Sometimes life will surprise you. Starring Mandy Moore ("A Walk to Remember"), Milo Ventimiglia ("Heroes," "Gilmore Girls") and Sterling K. Brown ("The People V. O.J. Simpson: American Crime Story)," this refreshingly honest and provocative series follows a unique ensemble whose paths cross and their life stories intertwine in curious ways. We find several of them share the same birthday, and so much more than anyone would expect. From the writer and directors of "Crazy, Stupid, Love." comes a smart, modern dramedy that will challenge your everyday presumptions about the people you think you know.

"Timeless": From Eric Kripke ("Revolution," "Supernatural"), Shawn Ryan ("The Shield") and the producers of "The Blacklist" comes this thrilling action-adventure series in which a mysterious criminal steals a secret state-of-the-art time machine, intent on destroying America as we know it by changing the past. Our only hope is an unexpected team: a scientist, soldier and history professor who must use the machine's prototype to travel back in time to critical events. While they must make every effort not to affect the past themselves, they must also stay one step ahead of this dangerous fugitive. Can this handpicked team uncover the mystery behind it all and end his destruction before it's too late?
