I love art dealers. In some ways they're my favorite people in the art world. Really. I love that they put their money where their taste is create their own aesthetic universes support artists employ people and do all of this while letting us see art for free. Many are visionaries.
Well I'm not a method actress by any stretch of the imagination so the best thing that I can do is be as real as possible and find whatever commonality in that character that I can see myself.
