Starring Diane Keaton and Brendan Gleeson, Hampstead is a heartwarming romantic comedy set around the beautiful Hampstead Heath in London, a quiet piece of countryside in a vast metropolis. Living in a lovely old apartment on the edge of the Heath, American widow Emily Walters (Keaton) feels like she is drifting aimlessly through life. Then she meets Donald (Gleeson), who has lived harmoniously on the Heath for 17 years in a ramshackle hut. When property developers attempt to destroy his home, Emily steps up to defend Donald in the escalating battle and soon finds that, despite his gruff exterior, there is something special about this gentle and unconventional man.
