DC fans have come up with a theory as to how Superman's Lex Luthor will escape from prison and appear in subsequent DCU movies – and well, it's so thorough, it's actually quite convincing.
The James Gunn-directed movie, which was released in July, concludes with Big Blue besting the bald baddie, before a post-credits scene teases the effects his pocket dimension technology had on Metropolis. In the clip, Superman (David Corenswet) and Mister Terrific (Edi Gathegi) bicker over two halves of a previously torn-apart building not being placed back together properly.
