Joe Biden is going all out to make sure his State of the Union address resonates with Americans … ’cause he’s taking tips from former Presidents — albeit, fake ones!

POTUS posted this video Thursday ahead of his SOTU later this evening, and he’s zooming with a bunch of actors who’ve portrayed presidents in film or TV roles — and yeah, he’s got some big names here chatting with him.

Morgan Freeman — who played President Tom Beck in “Deep Impact,” as well as Pres. Trumbull in “Angel Has Fallen” — reflects on his character having to deal with a looming meteor threat … saying amid the crisis, people found solace in his message of hope.

Bill Pullman — known for his role as President Thomas J. Whitmore in 1996’s “Independence Day” — looks back on his character’s battle against invaders from outer space … noting fear and chaos had a unifying effect on people.

As for Tony Goldwyn — who played President Fitzgerald Grant III in “Scandal” — he admitted his character behaved pretty badly while in office. But here’s the kicker … he advised Joe that if he just told the general public they made him a better man, they’d eat it up.

Michael Douglas, meanwhile, had some poignant advice to share … emphasizing that love and compassion are strengths, not weaknesses, and urged Biden to utilize his first lady, Jill, to his advantage. He played President Andrew Shepherd in “The American President.”

Geena Davis — famous for her role as President Mackenzie Allen in the TV show “Commander In Chief” — revealed that every week her character faced a new crisis, and the number one lesson she learned was that there’s no crying in politics.

JB was clearly impressed by GD’s portrayal, telling her she did one helluva job. And with a touch of humor, expressed his hope that his politics wouldn’t make anyone else cry. The one big actor he was missing from the lineup is obviously Martin Sheen … ‘West Wing’ anyone?

In any case … wise words from fictional Presidents, indeed!
