Kevin: I just try to write what I want to see. I tried to do that with 'Scream' and with 'Summer.' I just try to tell a compelling story.
Kevin: What I loved about 'Summer' was that they were these four bright kids with a wonderful future. In a way, she was the one with the brains, and then you have the beauty queen and the jock and the introvert.
Kevin: Typically in horror films the character just services the plot, and you really are just going from 'point a' to 'point b,' just so that you can end up at 'point c.'
Kevin: There's going to be a trailer in the theater like this coming summer, and it is just going to be a black screen, and all you will hear is that music.
Kevin: 'Summer' will be undoubtedly compared to 'Scream,' which is unfortunate, because this is a much more serious film.
Kevin: I think that our target audience today is just so savvy, so I try to write all of my characters so that they are self- aware.
Kevin: And that's what I liked about it, because they are, in the beginning, your little beautiful stock figures, who then make a decision to preserve their futures, but the decision they make isn't completely right, and it destroys their futures.
Kevin: I always wanted to direct. That's my passion. I was an actor. That went nowhere. I tried directing theatre. Nope. I wrote this movie called 'Killing Mrs. Tingle.' Sold it. It sat on the shelf. My unemployment dried up. I couldn't get work. I had borrowed money from all my friends. I wrote 'Scary Movie' (later retitled Scream). Just banged all it out, as fast as I could.
Kevin: Dawson's Creek has always been very personal and autobiographical; I live and breathe in all the characters...Dawson represents the filmmaker and dreamer, the Spielberg-obsessed idealist who views the world optimistically; Joey represents more of the cynical, angry side as well as my roots and upbringing; Pacey represents the joker in me; and Jen, the rebel. This year we added two new characters to the mix: Andie represents my overachieving, sometimes-manic personality and, in Jack, I wanted to create a character to represent my sexuality, which is my greatest asset in life.
Kevin: I'm not a real writer, I'm a screenwriter.
