As was noted not long ago by both executive producer Marc Guggenheim and director James Bamford, production on Arrow season 5 is now well underway.
The image of Amell shows Oliver with much longer hair than he had at the end of season 4, in both the present-day storyline as well as the flashbacks.
The season will kick off with ‘Legacy,’ a title that carries an appropriately weighty connotation to it, as the series that launched The CW’s Arrowverse ventures closer to its one hundredth episode.
Whether the implication was intentional or not, this image could serve as a tacit reminder of the show’s intentions to get back to its roots.
