Eric: I have this big pink cross to bear. I absolutely loved playing Will. There was nothing hard about it. It was wonderful. But the only downside is the aftermath. I meet all these film executives who tell me how much they loved Will and Grace and say they never missed an episode. Then they say, "so what can we do for you?" What they could do for me is hire me to play someone else.
Eric: I never felt cool growing up. I was a bit of an outsider, but I discovered theatre very early on, which got me through. When I read the script for Will & Grace in 1998, I knew I was the only guy for the part. Not because of his sexuality, but in every other way, I'm just like Will Truman.
(when asked what's the best thing about being Canadian)
Eric: George Bush doesn't run our country.
Eric: (asked to reveal his favourite "Will And Grace" episode) The Kid Stays Out Of The Picture. This was when Will thought they were going to have a baby together and Grace backs out because she's met Leo (Harry Connick Hr). We have this great, big screaming match the audience didn't see coming - which we did perfectly on the first take, by the way!
Eric: (on saying goodbye to "Will And Grace") It feels bizarre - a bit like the end of high school, where you think you know what it's going to be like to be an adult, and you don't! It's going to be very strange to wake up every day and not have this job and these people in my life.
Eric: As a television actor, there's a power you're given to use your image to do something valuable. As a parent, these messages are particularly important to me.
Eric: Will isn't a screaming queen - that's Jack's part. They needed someone to play the part for America. It's just not the same as Britain. To have a gay character as a lead is risky.
Eric: If you're doing an hour-long show, you're working movie hours, doing a 12-15-hour day. We work three or four hours a day, and get every third or fourth week off to give the writers time to write. It's the cushiest job in Hollywood.
Eric: I'm doing a very funny show in which we talk about issues. I speak at Aids charities and things. It's great to do something fun with our days and yet we're told we're doing something important.
Eric: I had played many gay characters before, but they were finite - guest characters in TV shows or characters in plays.
