Really, the measure of a man is when they're tired and exhausted.
Around '93, I had to get a couple of jobs. I had a job for a while working at a gym, just so I could work out for free, because I knew if I didn't exercise, I'd go crazy. It's the key to my mental health, actually.
There are a lot of times that if a detail in a scene or a beat, feels unnatural, they'll allow me to explore another direction to go until we're all comfortable with what we are doing.
I think what's always been interesting to me than the science and the criminality with this job is what happens to your persona, your disposition, after day in and day out dealing with life and death.
I think we take for granted police officers and detectives that walk into some pretty heinous situations, and they really have to be very brave. So I love playing a character that's very brave - someone that kind of dives in the fire to figure out what's happened.
Any time you put a cast like this in compromising circumstances or shake it up a little bit, I think we're all pretty close so we draw on real emotion.
Most of my stuff before CSI was kind of the jerk boyfriend, so I thought this was one of those deals, where these two have a thing going on, so we had a scene where they make out.
I think my character's getting to the point where he can't even eat spaghetti with red sauce anymore, where he has horrible nightmares, he can't sleep anymore.
