A long-lost avant garde painting has returned to Hungary after nine decades thanks to a sharp-eyed art historian, who spotted it being used as a prop in the Hollywood film Stuart Little.

Gergely Barki, 43, a researcher at Hungary’s national gallery in Budapest, noticed Sleeping Lady with Black Vase by Róbert Berény as he watched television with his daughter Lola in 2009.

“I couldn’t believe my eyes when I saw Bereny’s long-lost masterpiece on the wall behind Hugh Laurie. I nearly dropped Lola from my lap,” said Barki. “A researcher can never take his eyes off the job, even when watching Christmas movies at home.”

Crazy story. Berény was said to have dated Marlene Dietrich and Anastasia, the daughter of Nicholas II.
