Actress Milly Alcock said the pose used in a promotional poster for Supergirl was inspired by the way squirrels land.

The revelation provides insight into the creative direction of the character's physical presence, using animal-like agility to define the Kryptonian heroine's movements.

During an interview on The Tonight Show Starring Jimmy Fallon, Alcock said that the specific posture in the released poster was a tongue-in-cheek reference to squirrels [1, 2]. She said the imagery resembled a squirrel landing, utilizing the animal as a playful visual marker for the character's agility [1, 3].

Alcock's approach to the role reflects a blend of superhuman power and quirky physical traits. The actress used the squirrel-inspired pose to add a layer of personality to the promotional material, moving away from traditional superhero stances [1, 2].

Beyond her current role as Supergirl, Alcock shared details about her early career during the talk show appearance. She said she began cold-calling agents when she was 13 [1]. This early initiative preceded her rise to international prominence and her eventual casting in the DC Universe.

The promotional poster has since drawn attention from fans who noticed the viral detail of the pose [3]. By acknowledging the inspiration, Alcock said she highlighted the deliberate, if humorous, choices made during the production's marketing phase [1, 2].
