Some actors, and especially the younger actors, they come into the job with a lot of attention on how they behave and everything when they're not working. Sometimes that can be unfortunate because the work call is pretty intense and the preparation for it. If your focus is there, then the actual doing of the job will be fun and enjoyable. But if you're so involved in trying to be interesting and a character and everything when you're not working, it can get in the way and people get goofed up.
I think that by now, in the very beginning when I first joined the show, General Landry was like a new kid in school. I was coming into a situation I didn't really know much about, and now, after a couple of years, the character's kind of mellowed and gotten comfortable working at the command center and very comfortable with his troops. What they always do with these shows is they always leave them open-ended. The SG-1 franchise has been so successful for the network, that they always want to keep it open, an option to do it again in some way, whether that's a movie or a series, or whatever.
I like to try to make the characters I play be as human as possible.
My favorite roles usually have to do with the story, if it's a good story I usually enjoy doing the character.
