Cliff Simon: (about getting the part of Ba'al on Stargate) After meeting with the executive producer about 8 months before the character of Ba'al was created we decided to wait until the right character was written into the story for me, so Ba'al ended up mine and I was very lucky.
((2006) about rumors that he would appear in Stargate Atlantis)
Cliff: I think I should clear up any rumors. I have been saying that I would love to go across to Atlantis, now that SG-1 is coming to an end. I know a lot of fans have started to write to the producers about seeing Baal in Atlantis, which is awesome of them. But as I said I have not been approached nor have there been any meetings involving me about Atlantis. Obviously I hope I do.
Cliff Simon: I do enjoy them as far as, what I said to the fans and the viewers, without them we wouldn't have a show. So I'm always appreciative of the audience. I will never not sign an autograph. I will never be rude to somebody, because I'll never forget that. I've been in the business for a long time. I've seen a lot of actors become like that. And it's just terrible because you don't put yourself where you are.
Cliff Simon: Your viewers put you there. Your fans put you there. You can never forget that.
