The 'Batman Vs Superman' movie has been plagued by numerous casting rumors. The only way to stop those rumors is to confirm the cast, which Warner Bros. did with Lex Luthor and Alfred. However, the only way to quash plot spoilers is to show the movie. Massive plot spoilers ahead, folks.

The original rumor came from the Latino Review's El Mayimbe. As Screenrant warns, El Maimbe  "..has previously been right about some things (the plot of The Avengers, the inclusion of Thanos) and wrong about other things (Christian Bale and Christopher Nolan coming back for Justice League). So it probably goes without saying that you should wait for some kind of official confirmation before you buy into these rumors wholesale."

The rumors are very broad, and sets the complete stage for the Batman Vs Superman conflict and where Lex Luthor stands between them. Needless to say, it is very different from what is established in the comics. For one thing, there is no direct connection between Batman and Lex Luthor. It was only through Superman. That's not the case here.

The rumors from Latino Review were already compiled into bullet points by Screenrant:

PLOT SPOILER ALERT!!!

"Lex Luthor will be bald. (Shaved bald, not follicly challenged bald.)

He's way into tattoos and has a sleeve of the Metropolis skyline.

He's the richest man in the world - a tech genius and ruthless businessman - and became a self-made billionaire at age 18.

In his teens, Lex was a "street tough" and the head of a street gang (hopefully, we'll see flashbacks of him and his buddies with their sleeves rolled up, switchblades in-hand).

Apparently, Bruce Wayne - sometime in the past - called Lex an "amoral, arrogant brat," so they don't like each other; Lex also resents that Wayne was born into wealth.

Bruce Wayne comes to town to help rebuild Metropolis after the battle in Man of Steel; he wants Wayne Enterprises to pool its resources with LexCorp. Lex agrees.

Lex thinks of Superman as an 'alien,' a 'trespasser' on Earth; Bruce Wayne thinks of Superman as an "impressive specimen." Whereas Lex believes Superman can (and presumably should) be killed, Bruce Wayne thinks they can resolve their problems peacefully. The report also heavily implies that Luthor guesses that Bruce Wayne is Batman."

The spoilers have been released. The proverbial grain of salt is still advised upon reading. Does it make an exciting premise? Will it actually turn out that way? May 6, 2016  is the date of truth!
