The still unofficially titled 'Batman vs. Superman' movie, which furthers the DC cinematic universe kick-started in this past summer's 'Man of Steel,' is one of the biggest deals in recent memory for Marvel's competitor.

As often happens with something as epic in scale as this cinematic crossover -- we're thinking of you, 'Star Wars: Episode 7' -- rumors upon rumors have been circling the webosphere, leading fans down fruitless paths. To help quell the storm of iffy information, here's everything we know (so far) about 'Batman vs. Superman.'

    What Is the Film Called?

    'Batman v Superman: Dawn of Justice' is the official title of this team-up, as seen in the announcement logo.

    When this Batman-Superman crossover movie was announced during the Warner Bros. and Legendary Pictures' panels at Comic-Con 2013, no official title was revealed, only the 'Man of Steel' insignia engulfed by The Dark Knight's. However, David S. Goyer, 'Man of Steel' and Batman-Superman writer, said the team has been throwing around a couple ideas. "... We’re actually not sure whether the title is 'Superman vs. Batman' or 'Batman vs. Superman,' but, yes, it’s–that rematch, that combination, the two guys onscreen and that’s happening.”

    When Will 'Batman vs. Superman' Hit Theaters?

    'Batman vs. Superman' will hit theaters on May 6, 2016.

    Originally Warner Bros. dated the film for July 17, 2015 -- a year already packed with such titles as 'The Avengers 2,' 'Ant-Man' (which moved to the vacant July 17 spot) and 'Fantastic Four' -- but changed their minds in order to give the filmmakers enough time realize their vision. Said Warner Bros. International Distribution President Veronika Kwan Vandenberg of the move:

    We know that there is already great anticipation building for the next super hero film from Zack Snyder, and we are equally eager to see what he has in store for Superman and Batman as they share the big screen for the first time ever.

    Who Will Star in 'Batman vs. Superman'?

    'Batman vs. Superman' will bring back 'Man of Steel' star Henry Cavill as Superman, and as for Batman ... well, chances are you already know Warner Bros.' pick -- Ben Affleck will don the cape next.

    Other additions also include Jesse Eisenberg as the iconic Superman villain Lex LuthorJeremy Irons as Alfred, Gal Gadot as Diana Prince/Wonder Woman, stage actor Ray Fisher as the half-robot Cyborg, 'Game of Thrones' vet Jason Momoa as Aquaman, and 'Argo' star Scoot McNairy in a mystery role. Holly Hunter, Tao Okamoto and Callan Mulvey will also play roles newly created for the film, while Amy Adams (Lois Lane), Laurence Fishburne (Perry White) and Diane Lane (Mrs. Kent) will reprise their 'Man of Steel' roles.

    Worth noting is that the previously mentioned Justice League members are said to make only minor appearances and help herald the future arrival of the 'Justice League' movie.

    Where Will 'Batman vs. Superman' Take Place?

    Set photos have revealed both Metropolis and Gotham cities will have parts to play as the settings for 'Batman vs. Superman.'

    Despite 'Man of Steel' having set up shop in Vancouver, WB received a film incentive for Detroit and around the state of Michigan. While the city recently declared bankruptcy, the upcoming 'Transformers: Age of Extinction' has already called Detroit home for its production, and 'Oz, The Great and Powerful' filmed there not too long ago. So is Detroit the new Gotham City?

    Who Is Behind the Wheel?

    Zack Snyder will return to the director's seat for the 'Man of Steel' follow-up, as well as the previously mentioned screenwriter David S. Goyer (Christopher Nolan's 'Dark Knight' trilogy), who's penning the script from a story he co-created with Snyder. Charles Roven and Deborah Snyder are producing, with Benjamin Melniker, Michael E. Uslan and Wesley Coller serving as executive producers.

    Frank Miller, the comic creator behind '300' and 'Sin City,' crafted 'The Dark Knight Returns' comic, which famously pitted Superman and Batman on the page. The Independent previously reported that he would have talks with Snyder about 'Batman vs. Superman.'

    What Is 'Batman vs. Superman' About?

    So far, no official plot descriptions have been revealed -- but here's what we know:

    Lex Luthor will be the villain of 'Batman v Superman: Dawn of Justice,' and is said to be a younger, more Mark Zuckerberg-esque version of the comic book iteration, with Lex Corp serving as a hip, up-and-coming company. (Appropriate, considering Eisenberg played Zuckerberg onscreen in 'The Social Network.')

    In the official casting announcement for Ben Affleck, Zack Snyder stated:

    Ben provides an interesting counter-balance to Henry’s Superman. He has the acting chops to create a layered portrayal of a man who is older and wiser than Clark Kent and bears the scars of a seasoned crime fighter, but retain the charm that the world sees in billionaire Bruce Wayne.

    Also worth noting is how WB chose to announce 'Batman vs. Superman.' At Comic-Con, Snyder came out on the Hall H stage and introduced one of his 'Man of Steel' stars, Harry Lennix, who played General Swanwick. The actor proceeded with a dramatic reading of a passage from Frank Miller's 'The Dark Knight Returns,' which Batman speaks to Superman: "I want you to remember, Clark, in all the years to come, in all your most private moments … I want you to remember my hand at your throat. I want you to remember the one man who beat you."

    While this is by no means an official confirmation that the story will be adapted from Miller's comic -- in which the two heroes do battle against each other -- it certainly seems to be taking its inspiration and tone from the work.

    The events of this film will no doubt set up what's to come in the 'Justice League' movie, as all the primary JGL members will make at least minor appearances in 'Batman vs. Superman.'
