Washington, June 14 Actor Ryan Reynolds has described acting with Sandra Bullock as "driving a Ferrari".

The two recently have shot a film together called 'The Proposal'; the story is about a tyrannical boss who enlists her assistant to help her not be deported to Canada.

Ryan is excited about the project and his equation with the beauty.

"This kind of chemistry and fireworks, there's nothing you can do to manufacture it, or edit it together. It's just there or it's not. And to have that every day was literally like driving a Ferrari around on set," Contactmusic quoted him, as saying.

In response, Bullock also praised her colleague, she said: "The person I met years ago through a friend is the same person sitting next to me now. No change in the humility, talent, kindness. He could've become an a**hole. But not a damn thing has changed, other than that his bikes get more expensive."

Sandra is married to Jesse James while Reynolds has Scarlett Johansson as his beautiful wife. (ANI)
