‘Supergirl’ spoilers: Who is joining Claire Holt in the casting rumor mill?

Even though the “Supergirl” series is not seemingly close to filming, the rumors mill is still churning out stories at a pretty steady pace about who will play Kara Zor-El.

Recently, there were rumors surrounding Claire Holt, which was an unsurprising name for many reasons. She is already familiar to Warner Bros. / CBS due to “The Vampire Diaries” / “The Originals,” she looks the part already, and she is within the age range of mid-to-late twenties that we hear producers are looking for (which seems a little old considering Supergirl is a “girl” and not a 30 year old woman).

So who is joining her now on the list of possible candidates? If you believe British publication The Sun, “Hollyoaks” alum Gemma Atkinson has tested for the part, and she is waiting to find out if she is going to move a step closer to landing it. While Atkinson may not be familiar to many Americans, this may work in her favor, given that there is something to be said for making someone iconic versus bringing on someone known for another major property. In casting Stephen Amell, “Arrow” proved that to be true. Grant Gustin was a little more well-known, but mostly only to diehard “Glee” fans for his short arc on the show.

It’s clear why Atkinson would want the part, and she may have a shot. She’s not a complete gamble thanks to her experience, and while she is a little older at 30 than Holt, she should be able to play younger without a problem. (Last we heard, the Kara character is going to be 24 at the start of the series.)

In the end, we really don’t care too much about the casting so long as they take their time, and ensure that they get the right person. From the outside looking in, it is admittedly very hard for us to say who is the right choice without seeing the auditions and the screen tests.

We will have more on the casting search as it continues, so be on the lookout for additional stories.
