Denzel Washington will forever regret turning down the lead role in Michael Clayton.

George Clooney picked up the part and was Oscar nominated for his portrayal of a law firm fixer in the acclaimed 2007 Tony Gilroy movie, and now Washington admits he was wrong to back out of the project.

He tells America's GQ magazine, "It was the best material I had read in a long time, but I was nervous about a first-time director, and I was wrong. It happens."
