François Audouy and Arianne Phillips, the production designer and costume designer of “A Complete Unknown,” both benefited from the pandemic- and strike-related delays that gave them more time to prep for James Mangold’s look at the first few years of Bob Dylan’s career in New York City. Not only did Mangold keep rewriting and improving the script, but the production design and costume teams had more time to figure out how to re-create the time, place and feel of a world that hasn’t existed for 60 years — though not through slavish imitation.
“I went into production after four years of marinating and learning about Bob,” Phillips said.
