People keep using the phrase “trained martial artist” as if it means anything. Especially coming out of Hollywood…
And even if she does have authentic martial arts training, why does that make everyone think that she must be cast with the intent of using that skillset? Actors often have wide ranges of experiences in their backgrounds that may or may not come into play for any given role…
I think it’s because we’re used to seeing actors with a martial arts background play characters defined by their stunts and fight scenes (ex. Ray Park, Jackie Chan, Donnie Yen), and being a more showy skillset, it would be far more requested in a casting call for an action/fantasy franchise than, lets say, playing the piano.
