I disagree with you about the movie clips. There are stiff requirements about who should lead the church. I am quite sure that godless atheists are not supposed to lead. So why invite them into the church to perform? Would you invite Britney Spears in to sing "Oops I did it again" just to illustrate Romans chapter 7 about the sin nature? I don't think so. It's the same idea with secular movies. If you like the story parable then tell it. But don't turn the church into a Hollywood advertisement.

To a point I agree with you. In fact, the one thing that concerned me about the Matrix clip was that they were somehow giving the movie credibility. However in the context of the meeting, two things calmed down my concerns. 1. Everyone there had seen the movie.
2. It was presented as something the movie had done unwittingly.
Regarding your Brittney comments. I agree and disagree and, no, my name is not Kerry. I do not consider secular music - by virtue of it being secular - to be bad. I take each song on it's own merit. All popular artists are complex individuals just like you and I. There is more going on under the surface than just the lyrics of one or two (or more) of their songs. Like all of us, they have made compromises, some more than others, but there is good and bad from all of them - and all of us for that matter.
But no, I wouldn't have her sing "oops..." in my church.
