One of the most impressive parts about Logan was one of its most closely guarded secrets: Hugh Jackman not only played the title character, he played his evil double too; a perfect clone of Wolverine known as X-24. This new character wasn’t featured in any of the marketing materials or even alluded to in any way. When he shows up late in the film he is a shock, and an effective extension of the movie’s themes about a man wrestling with his nature as a killer (and, possibly, a monster).
The role of young mutant Laura (aka X-23) in Logan is a demanding one, to say the least, and it’s not surprising that finding the perfect actor for the part was equally challenging for director James Mangold. He needed to find a 12-year-old actress with acrobatic and martial-arts skills who could speak English and Spanish, and, perhaps most important of all, hold her own opposite Hugh Jackman. That’s a pretty specific list of requirements, but Dafne Keen fit the bill (and then some), and now you can watch one of the incredibly impressive (and profanity-laden, FYI) audition tapes that led to her breakout role.
