When it comes to Oscar precursors, the SAG Awards, handed out by the Hollywood actors’ guild SAG-Aftra, always give us the most to chew over. This guild is comparable to the academy in terms of size and membership, and most of the five actors nominated in each individual category will go on to be nominated for Oscars, too.

But where will the two groups differ? And are there contenders who missed with SAG but can still pull off an Oscar victory, as Regina King, from “If Beale Street Could Talk,” did last year when she won the supporting actress Academy Award? Let’s take a closer look at the nominations announced on Wednesday to see who’s got the heat to go all the way.

Movies

Outstanding cast

“Bombshell”

“The Irishman”

“Jojo Rabbit”

“Once Upon a Time … in Hollywood”

“Parasite”

This nomination is a major coup for “Parasite,” which will contend for SAG’s top award despite the fact that none of its individual actors were nominated. This is not an awards body given to nominating foreign films — “Parasite” is the first such movie since the 1998 film “Life Is Beautiful” to score a SAG cast nod — and it’s proof that “Parasite” will have the large academy contingent of actors on its side when mounting a best-picture bid at the Oscars.

“Once Upon a Time … in Hollywood” and “The Irishman” were expected picks in this category, but “Jojo Rabbit” was an on-the-bubble contender and “Bombshell” was a big surprise: Female ensemble casts can have trouble popping through at SAG, as Greta Gerwig found out when her take on “Little Women” was snubbed across the board.
