The fourth season of This Is Us is premiering in a few weeks and NBC just released a new trailer, which reveals a lot of new cast members!

One of the most surprising cast additions is writer and director M. Night Shyamalan, who can be seen in a brief moment in the trailer.

We already knew that Once Upon a Time‘s Jennifer Morrison is joining the show in a major recurring role and we have our first glimpse at her in character.

When They See Us‘ Emmy-nominated actor Asante Blackk is among the new stars and Deadline surmises that new cast members Marsha Stephanie Blake and Omar Epps will play his parents.

Other new stars include Animal Kingdom‘s Bahara Golestani, Psych‘s Timothy Omundson, Queen of the South‘s Julian Silva, Doubt‘s Auden Thornton, and Revenge‘s Nick Wechsler.

In the trailer, Mandy Moore‘s Rebecca is seen telling Milo Ventimiglia‘s Jack, “It’s actually kind of terrifying how a single cross with one person who you’ve never met can change everything.”

The fourth season of This Is Us premieres on September 24 with an extended episode.
