India, July 6 -- Jennifer Aniston is giving fans a glimpse of what's to come in Season 4 of The Morning Show, and it's going to be anything but light.

"The Morning Show is just a beast to film. It's layered, it's complicated, it's emotional, it hits on a lot of topics and current events - so let's just say, it's not Friends," Aniston told PEOPLE in an exclusive interview, referring to the iconic sitcom Friends, in which she played Rachel Green from 1994 to 2004.

The Morning Show, which launched in 2019, stars Aniston as news anchor Alex Levy. Now 56, she says the role, along with her job as executive producer, is demanding but worth it.

Alongside Reese Witherspoon, Aniston is involved in nearly every aspect of the show.
