Edward Norton has revealed Timothee Chalamet was "relentless" in his approach to play Bob Dylan in 'A Complete Unknown'.
The 55-year-old actor appears opposite the 'Dune' star, 28, in the upcoming biopic as folk singer Peter Seeger, and has now shared that Chalamet – who portrays Dylan – took playing the music icon very seriously, and shut off as many distractions as possible to fully immerse himself in the role.
