A big Supergirl announcement is coming soon, according to Ali Adler who is a write/executive producer on the new series.
Adler took to her Instagram account yesterday to tease, "#100happydays day 69 big #supergirl news coming soon!"
So with today day 70, that would leave about a month until the big Supergirl announcement, somewhere around February 20th.
Maybe we'll get a casting announcement and premiere date?
Supergirl is set for CBS, and recently dialogue from a screen test hit the net revealing conversations about Superman, Krypton and more.
