They don't need anyone with clout, they'd be more interested in someone who can deliver a show on time and within their ideal budget (something that a formerly unknown producer named Rick Berman was able to do very well.
Thats pretty much what I meant by clout, maybe credibility would have been better. A show runner who has made money lately.
The cost of producing Star Trek is not the holdup. It's the cost vs projected revenues. CBS would spend big if it had a reason to believe the revenues would be even bigger, and even then it would have to beat that cop show they could do instead.
Foreign markets aren't going to solve this problem because any money CBS could make from space opera, they could make even more with a cop show. Take all those co production schemes you guys are thinking of, and just insert a CSI knockoff in there instead. Why wouldn't that work for CBS even better? CSI being the supposedly most popular TV series in the world and all. Or, maybe they should try their hand at a telenovela style soap.
The main problem is that nobody at CBS is championing a new show. When that changes, we 'll get a new show. Till then, everyone is content to spend their time on other things. There are plenty of other, easier ways for CBS to make money.
