The path a movie takes from script to screen is often an arduous one filled with schedules that need to align, shooting locations that need to be secured and, of course, tons and tons of unused concept art. James Mangold’s “Logan” might have hit theaters just two weeks ago, but the film -- with its distinctive style and decidedly dystopic, downtrodden tone -- didn’t always look like what made it onto the big screen. Some recently released concept art for “Logan” shows how the film's look evolved from the panning process and, in some cases, how it stayed the same.

The art comes via ScreenRant, courtesy of Christian Cordella, whose portfolio includes a dizzying array of major action films and television shows, including “Captain America: Civil War” to HBO’s “Game of Thrones.” 20th Century Fox brought Cordella on to do concepts for “Logan’s” four main characters, and -- while there are certainly some similarities between his art and the characters as they appeared in the film -- the differences are apparent.

Perhaps the biggest difference is Wolverine himself, who appears more youthful and spry in illustration than his on-screen counterpart. Jackman’s Wolverine sports a bushy, graying beard and thick, salt and pepper hair. In comparison, Cordella’s depiction looks more in keeping with the wild-eyed Wolverine as seen in “X-Men: Apocalypse.” Nonetheless, the illustration conveys the feeling of a man preparing for his last stand against the forces of evil, which is certainly in keeping with the theme of “Logan.”

The only other major deviation from the final cinematic product is Professor Xavier, who rarely finds the time to smile or look like his old, confident self in “Logan.” The costume in the second illustration, which shows the professor in a blanket, white undershirt and loose-fitting sweater, is the closest to Patrick Stewart’s classic depiction of the ailing mutant headmaster, aside from the blissful smile.

“Logan” is Hugh Jackman’s final outing as the iconic “X-Men” character Wolverine. The film finds the claw-wielding antihero living is isolation with his mentor, Professor Xavier, in the near future when mutants have become endangered. The duo’s cover is blown, though, when a mutant with powers and adamantium blades similar to Wolverine's shows up. Wolverine must decide to stand with the girl or pass her by in her hour of need.

Currently in theaters, “Logan” is directed by James Mangold and stars Hugh Jackman, Patrick Stewart, Boyd Holbrook, Stephen Merchant, Richard E. Grant and Dafne Keen.
