Eva Mendes almost killed Will Ferrell on the set on The Other Guys.
The actress plays Ferrell's wife in the movie and whilst filming a fight sequence she picked up a real knife instead of the prop.
Speaking to People magazine the actress said: "Once we got the scene down, we were told to improv (improvise). We got into a little tug of war, and I picked up what was supposed to be a prop knife.
"It was actually a carving knife from our meal. I lunged at him, and I was really proud of myself [before I realised my mistake].
"When we cut, Will said, 'Wow, usually we have to co-ordinate that with the stunt department'. It could have gotten ugly in a second. I almost killed Will Ferrell!"
The Other Guys sees Ferrell team up with Adam McKay, together they produced Anchorman, and the cast list also includes Mark Wahlberg, Samuel L. Jackson and Dwayne Johnson.
The Other Guys is released 3rd September.
