The British actor regularly watched the daytime TV show in his trailer while filming Skyfall, a source told The Sun.
"Daniel always wanted Homes Under The Hammer on when he had time to see it," the insider said. "A lot of people were surprised he was a fan given his serious image.
"When one of the assistants came into his dressing room and found him watching it, they told him they'd find him something else to watch. But he said, 'No - leave it, I really like it'."
Homes Under the Hammer host Martin Roberts took to Twitter to celebrate his celebrity fan, asking followers to think of Bond-themed property names.
Among the favourites included 'On Her Majesty's Secret Survey', 'Roommaker' and 'A View To Kill For'.
Skyfall will debut in UK cinemas on October 26, and in the US on November 9. Watch the trailer below:
