Oscar buzz in my ears

SO Meryl Streep, ever meet Katharine Graham, whom you immortalized in “The Post”?

“No,” she told me. “But I spoke repeatedly with her longtime assistant. And got to know Mrs. Graham’s character, personality, habits, her thinking, her ways. I also researched everything I could about her.”

Hollywood mutters: Interracial “Get Out” didn’t play “real” . . . “Shape of Water” floated because of marketing genius Roger Corman . . . “Billboards” dealt with Woody Harrelson, who dies, but all supporting characters could’ve been leads. Well-written . . . “Lady Bird” was up because of ladies Greta and Saoirse. Frances McDormand had the best character to play and didn’t screw it up . . . Big betting on Gary Oldman or Denzel. Supporting: Sam Rockwell. No competition. Also Laurie Metcalf. Allison Janney? “Great — but a one-beat character.”

Post-Oscar party at NYC’s Copacabana. Live performances, local filmmakers, industry veterans. Lindt chocolate. Goodie Girl cookies. Food, great. Nobody cared who won.

“Molly’s Game” folded her cards but Molly

Bloom’s en route to career No. 2. “Build a network. Put female entrepreneurs together. I’m building office space for women” . . . WHAT’S it like for nonwinners? Longtime forever bigtime star Alan Alda: “When ‘M*A*S*H’ was canceled, I was depressed. Felt like I stepped off a speeding train.”
