In an interview with PeopleTV, Atkinson, 63, revealed that he'd actually been left with months of back pain after shooting the scene.
"Even though it was a prop, that turkey was fantastically heavy," Atkinson said. "And it had terrible repercussions on my neck and down my back for months afterwards. A vicious turkey prop injury."
The actor — also known for his work in the Blackadder TV series and Johnny English movie franchise — also opened up about how he'd come up with the idea for the show.
"(Mr Bean screenwriter) Richard Curtis and I met when we were both students at Oxford, and we'd already done some visual sketches for a stage revue we were doing," Atkinson said.
"We didn't call them 'Mr Bean' sketches, but they effectively were. And I'd discovered by then that I could express myself visually once I'm asked to tell a comedic story, without words."
The TV series went on to become a global hit, and later inspired two movies and an animated cartoon spin-off.
