Personally, I think the cast could include the following: Christopher Eccleston Robert Carlyle, Alan Ford Liz White Tegan Summer Mina Anwar. That would make up a good diverse British cast with good acting credentials all the way around! I also don't think there should be any issues with having an American recurring character or what not, as long as the main cast is British. Why should Americans be relegated to victims and criminals? Not all folks from the Latin Countries are criminals on CSI: Miami, for example. I think taking that kind of tack is rather hateful actually.
