I've been waiting for this one for what seems like a decade.
Was initially attracted to the Nikola Tesla, Thomas Edison, George Westinghouse Jr conflict, but had forgotten how much of the cast has appeared in DC and Marvel movies. Dr. Strange fights General Zod with the help of Beast and Spider-Man.
Should finally release this October.
