It is a film that explores the decline of manufacturing jobs in the Midwest.
The documentary won in the best feature-length doc at the glitzy ceremony earlier this month.
And, after the win was announced, Michelle took to social media to pay the emotional tribute.
She wrote: “Congrats to Julia, Steven, and the whole crew on winning Best Documentary for #AmericanFactory, Higher Ground’s first release!
“So glad to see their heart and honesty recognised—because the best stories are rarely tidy or perfect.
“But that’s where the truth so often lies.”
