The “Bridesmaids” cast has reunited at the Dolby Theatre as Oscar presenters. On Saturday Kristen Wiig, Maya Rudolph, Ellie Kemper, Rose Byrne and Melissa McCarthy ran through their lines and fine-tuned the timing. Byrne rehearsed with the group while also holding the distinction of being an acting nominee. Other presenters keep it casual too, with some wearing sneakers including Javier Bardem and Adrien Brody. The room felt calm as crews work through final checks, just 24 hours before the 98th Academy Awards. Conan O’Brien is returning to host the show, which will air live on ABC at 7 p.m. Eastern.
