Denise: (on the love scene between her Trek character and that of Data played by Brent Spiner) Well, you know Brent is just a great guy and a lovely person and so funny that it was just ridiculously funny. We just made light of it and had no idea that it would have such a resonance with people. I had to just worry that the outfit I was wearing would stay in place! That was my biggest fear, and then not laugh. Because Brent's face was just like Pinocchio or something! It was just so funny, we just had such a ball doing it.
Denise Crosby: (on leaving Star Trek: The Next Generation) Leaving the show was a really difficult decision to make. It was purely an artistic one. I was very, very frustrated as an actor on the show and I felt straight jacketed. I always kind of use the comparison of being drafted by the major leagues and then being benched so I just felt like I needed to keep going you know, keep running, but I had no idea that I would still have this continuous involvement (with Star Trek) you know.
