Vanessa Kirby's Mr. Jones First Trailer And Poster

Title - Mr. Jones
Studio - Samuel Goldwyn Films
Starring - James Norton, Vanessa Kirby, Peter Sarsgaard
Writer - Andrea Chalupa
Director - Joseph Mawle

Already released in other countries, the American trailer has just been released and it looks like a small but interesting thriller. And when you have Kirby and Sarsgaard, but chooses an unknown, James Norton, to lead; I'm interested to find out who this actor is.
