CBS still hasn't chosen which actress will play Supergirl/Kara Danvers in their new television series based on the DC Comics' character, nor have they cast anyone in any role. So, it is not surprising that audition videos for the show would appear online and five of them have. Check them out below, but be warned that some of the dialogue might actually be from the show, thus there could be... spoilers! Take for example the first three videos, they feature actors reading for the part of photographer Jimmy Olsen. In them, Jimmy is recounting the heroics of Superman saving a family from a burning building to Kara, who wanted to know if Jimmy was scared of Superman's superpowers when he first observed them. Based on the scene, Kara will be working alongside Jimmy. The next video is of a young actress auditioning for Kara/Supergirl She is reading the same dialogue. Eh, she was okay. The final video is an actress auditioning for Kara's foster sister, Alexandra "Alex" Danvers. In this scene, Alex is scolding Kara for rescuing people in a train. It is Kara's first use of her superpowers out in public and Alex isn't happy about the possible ramifications.
Update! Spoiler TV (click here) has added more audition videos and has even transcribed the dialogue. To view them all, or to read the transcript click on the link above or below.
