Charlie Rose has really gone out of his way to get a lot of architects on his show. Search his website and you will find great interviews with Philip Johnson, Frank Gehry and many others.
Here is a link to a recent show focusing on Jean Nouvel who has designed, among other things, that really exciting 75 story building next to the MoMa in New York. Enjoy:
