Firsht released a five minute reel of his recent work on YouTube over the weekend. Around the 2:32 mark in the video above, we see Jesse Eisenberg as Lex Luthor against a green screen. The clapper behind him reveals that Firsht was working the camera and that Joss Whedon was the director. It appears to be dated September 23, 2017 as well.
