"Lincoln" scored nominations in the lead actor category for Daniel Day-Lewis, supporting actress for Sally Field, supporting actor for Tommy Lee Jones and best ensemble in a motion picture.
And "Silver Linings Playbook" picked up nominations for lead actor Bradley Cooper, actress Jennifer Lawrence, supporting actor Robert De Niro and best ensemble.
Arguably the biggest winner of the day, however, was 77-year-old Maggie Smith.
The two-time Oscar-winning British actress scored the most SAG nominations Wednesday -- four in all.
She picked up two nods -- best supporting actress and ensemble -- for the feature film "The Best Exotic Marigold Hotel," a dramedy about a group of British retirees who move to a hotel in India.
She also picked up best supporting and ensemble nods for playing the officious dowager in "Downton Abbey."
The nominations come during one of the mostly closely watched weeks of the awards season: It's literally make-or-break for Hollywood and the films and performers who are jockeying for recognition -- and possibly Oscar gold.
Monday kicked off with the announcement of nominations for the Critics' Choice Movie Awards, followed quickly by Wednesday's SAG nominations.
In just 24 hours, the Golden Globe nominations are to be announced.
When the dust settles, those films and performers that emerge are instantly catapulted to front-runner status leading up to the Academy Award nominations, which are to be announced Jan. 10.
Although SAG winners often go on to win the Academy Award, it's not a given.
Just this year, Viola Davis won the SAG Award for best actress for "The Help," but Meryl Streep took home her third Oscar for "The Iron Lady."
In other film nominations announced Wednesday, "Argo" rounded out the ensemble nominations, with Alan Arkin also scoring a supporting actor nod.
Joining Day-Lewis, Cooper and Jackman in the lead actor category are John Hawkes for "The Sessions" and Denzel Washington for"Flight."
Notably missing from the list of nominees was Joaquin Phoenix for "The Master." (Just earlier this week, Phoenix had won the L.A. Film Critics Assn. best actor honors.)
Vying with Lawrence in lead actress field are Marion Cotillard for "Rust and Bone," Jessica Chastain for "Zero Dark Thirty," Helen Mirren for "Hitchcock" and Naomi Watts for "The Impossible."
Rounding out the supporting categories are Javier Bardem for "Skyfall," Philip Seymour Hoffman in "The Master," Helen Hunt in "The Sessions" and Nicole Kidman for "The Paperboy."
