Dafne Keen impressed moviegoers the world over with her portrayal of the short-tempered young mutant X-23 in 2017's ultra-violent, R-rated X-Men film Logan. Keen wasn't the only preteen girl to audition for the part of Laura Howlett, however—the young actress faced competition from Stranger Things' Millie Bobby Brown.
In an interview with Westworld's Evan Rachel Wood, for Variety's "Actors on Actors," Brown revealed that she went out for the part of X-23—which she considers to be her best audition—with Hugh Jackman. Despite her intense preparation and proud audition, however, Brown as X-23 ultimately wasn't meant to be.
Though presumably disappointed in losing the major Hollywood role to the younger Keen, Brown said she watched Logan and credited her competitor's performance as "incredible." Incredible it was, indeed—and it's hard to imagine anyone playing X-23 more fiercely and ferociously than Keen.
