Canadian film-maker Sarah Polley has shared a "cruel" April Fools' joke played on her by none other than her 11-year-old child.
Ednews reports citing Metro that a letter turned up on Saturday morning, reading "We say this to you with the deepest regrets: the Oscar you received was given by mistake."
Polley won the best adapted screenplay for Women Talking at the 95th Academy Awards in Los Angeles last month.
The letter, posted on Twitter, asked her to "mail it back" to California.
It said she could keep the award for one more week so she could "enjoy its presence" in her home.
But ultimately, it needed to be returned so it could go to the "rightful" winner: All Quiet on the Western Front.
"We are sorry for your loss, but it is only fair that the play with the real best adapted screenplay gets the Oscar."
