In this new promo for Supergirl, we get to see lots of great footage revolving around both Clark Kent and Superman as he arrives in National City to help his cousin out. It definitely seems like the hero will be a key part of the show when it premieres on The CW next month, and while his future beyond the first couple of instalments is a mystery, Tyler Hoechlin appears to have been really well cast here.
Keep your eyes peeled on this trailer and you'll also notice that Lena Luthor and LuthorCorp also make an appearance, while there's a mention of Gotham City too. As far as I can recall, this is the first time Supergirl has mentioned that iconic location, and if the events of Flashpoint have brought her into the Arrowverse, that could lead to some interesting developments and debuts somewhere down the line.
