There are nominations for the entire cast of A Star Is Born. Also the protagonists Lady Gaga and Bradley Cooper are nominated, just like Sam Elliott. He can have the award for the actor with the best supporting actor win.
Bradley Cooper has strong competition from Rami Malek, the protagonist in the Queen biopic Bohemian Rhapsody. That film has two nominations to address, including that for the entire cast. Black Panther, BlacKkKlansman and Crazy Rich Asians things at that price.
