Rex: (about being respect and being famous) I want to be respected by my peers and try to keep my work fresh. I came out here to work. If I'm fortunate enough and lucky enough to have celebrity go along with that, that's fantastic. Being famous was never in the cards for me.
Rex: (about his goals) My goals right now are to not get complacent with my acting, and work on it as hard as I can, and just get to the next level.
Rex: (about his friends and family supporting his career change) My best friend and my family knew I could get a job acting. They were very supportive.
Rex: (about working with David Caruso) I love working with David; he's one of the smartest guys I know. You have to be prepared when you're working with him.
Rex: (about his new found fame) It still blows me away sometimes that somebody even wants to interview me or wants an autograph or a picture with me. I'm thinking, okay, well that's cool, but I wonder why. Sometimes I have to remind myself.
Rex: (about his family) I was raised in a small town in Texas, and I'm fortunate enough to have a very supportive family. They taught me values and morals that I think have carried over into every part of business that I've been in. I have to give credit to them, because they taught me how to treat people well, they taught me how to respect people, and I think that's really helped in my career.
Rex: (being on CSI: Miami) I didn't start off the show. I was hired on the sixteenth episode, and not even as a regular. I was hired for one episode. They liked David Caruso's and my chemistry together. My agent called and said they wanted me for one more episode. That turned into nine in a row in the first season. In the second season I did thirteen, and in the third season I did nineteen. And then last year, they finally stepped up to the plate and signed me on as a regular. It's been fantastic.
Rex: Well, first I must say I love to cook. Growing up in Texas subjected me to a lot of outdoor cooking. Through the years I've been fortunate enough to meet and cook with many talented chefs.
