“If I say to you the king died and then the queen died, that’s a sequence of events. If I say the king died and the queen died of grief, that’s a story.” -- David McCullough

GKW Filmworks, Inc. is a collaboration between Trevor Ristow and Stephen Thomas Previtera, two friends who share a passion for history and storytelling.


History need not be a dry sequence of events. It is full of war, courage, revolution, leadership, heroes, villains -- even romance. It should entertain as well as inspire.


GKW Filmworks is dedicated to telling history as lively stories that engage audiences around the world and across generations.
