Sean Penn says he hadn’t felt joy making a movie in 15 years. That is until his neighbor, Dakota Johnson, knocked on his door with a script and an invitation to be her co-star. “I felt like you would feel getting your first movie,” Penn recalled of his initial response to reading “Daddio," which hits theaters Friday. But the film that re-enchanted Penn with the art of making movies is by no means a typical Hollywood flick. Instead, “Daddio” is an austere portrait of an ephemeral, serendipitous human connection.
