One will notice throughout The Defenders that Colleen has her hair pinned up in a ponytail in all of her scenes, and there are no scenes of her with her hair loose. According to Jessica Henwick, this was done so that audiences wouldn't confuse Colleen with Elektra, as Élodie Yung wears her hair loose through all of Elektra's scenes. Ironically, during her scenes in Daredevil, Elektra usually has her hair pinned up during fights.
