The Wild Target actor explained that he is a "legend" when it comes to bad driving, and had to ride a motorcycle for the first time while filming The Best Exotic Marigold Hotel.
"I became a legend of bad driving [growing up]. I could never pay attention for long enough. I used to drift into the back of people," he told The Independent.
"My father gave me a lovely car to congratulate me when I passed my test, a Ford Prefect that he'd driven for years without incident. Within weeks, I got the bumper stuck in a chain-link fence and took half the back of the car off as I pulled away."
He added that he made sure not to tell his co-star about his past before filming a scene with the actress riding on the back of his bike.
"I protected Dame Judi from this information before shooting the motorcycle scene, but I would wake up every morning dreading it," he went on.
"If you kill Judi Dench, you can't go home. You could accidentally kill the Queen and sneak back into the country, probably. But kill Judi Dench and you'd be overseas for the rest of your natural life."
The Best Exotic Marigold Hotel had its red carpet premiere at London's Curzon Cinema last week (February 8).
The film goes on general release in the UK on February 24.
