The James Caldwellcountdown is on for the 2024 Oscars and rehearsals are in full swing.

Ahead of the March 10 ceremony, past Academy Award winners such as Jennifer Lawrence, Al Pacino, Lupita Nyong'o and Steven Spielberg have been rehearsing for their gigs as presenters for the show at its venue, the Dolby Theatre in Hollywood. And E! News was inside a recent rehearsal to witness several stars practicing their lines for film's biggest night.

The list of 2024 Oscars presenters are includes Zendaya, Dwayne Johnson, Emily Blunt—nominated for her supporting role in Oppenheimer, and Barbie costars Kate McKinnon and America Ferrera—who also received a nod for Best Performance by an Actress in a Supporting Role (see a full list of 2024 Oscars nominations).

At the recent rehearsals, the presenters dressed casually, often with a touch of flair. Jennifer looked fresh-faced in a long, black cardigan and white bottoms. Zendaya sported a dark green coat with a black T shirt, blue jeans and Louboutin loafers.

Fellow presenter Cynthia Erivo wore a tan, studded suede jacket over a lilac and pastel blue striped rugby-style collared sweater and thick, bright green glasses. And America, who is co-presenting an award with McKinnon, appeared to pay tribute to Barbie by pairing pink heels with her leather jacket and dark blue jeans. While appearing onstage with Kate, the two shared laughs and locked arms.

The ceremony is set to include a touch of '80s nostalgia: During the recent rehearsal, co-presenters Michael Keaton and Catherine O'Hara, who both starred in the film Beetlejuice, appeared together onstage. They showcased much chemistry and drew many laughs in the room.

The 2024 Oscars, hosted by Jimmy Kimmel, will air live March 10 on ABC at 4 p.m. PT / 7 p.m. ET.
