We’re getting a look at an extended version of a Wonder Woman promo that aired tonight during Supergirl‘s season finale, with Supergirl stars Melissa Benoist and Chyler Leigh, along with recurs Lynda Carter and Teri Hatcher. Set to a version of “These Boots Are Made For Walking”, the promo features the four, all wearing pretty amazing boots, unexpectedly meeting up in National City’s alien bar.
