I know when my films suck, says Ashton Kutcher

London, February 16 (ANI): Ashton Kutcher has revealed he relies on his friends instead of the box office to find out whether or not his films were good.

The 35-year-old actor said he knows exactly what films he's done that weren't up to the mark and he also knows the ones that are good, that people like, the Daily Mail reported.

Kutcher explained that it's not because of the box office, which he says is not going to tell you the truth - but because he has friends that don't hold back and don't depend on him for money or employment.

"They're just friends. Friends tell the truth. My big thing is, Fail fast. If you're going to f*** up, get it over with," he added. (ANI)
