Principal photography begins shortly on director Zack Snyder's Man of Steel sequel, and still so many questions remain. Is Lex Luthor in the film? How much Wonder Woman will we see? When will we get our first look at Ben Affleck as Batman?

While we wait for official news on those questions and more, Batman-on-Film.com founder Jett took to his website over the weekend to provide some answers of his own. None of this is gospel by any means, but in Jett's defense, he has a long and solid track record where Batman's concerned — in other words, take the following with a pinch of salt, but a smaller pinch than usual.

According to Jett, Lex Luthor is indeed in the film, as is another as-yet unnamed villain. Martian Manhunter and Aquaman will not appear, despite the inclusion of some of their Justice League pals. As for Wonder Woman, Jett suggests her role is "on par with Scarlett Johansson's first appearance as Black Widow in Iron Man 2," with set-up potential for a future solo film. Further, Jett bets "a year's pay in Monopoly money" that the DC Cinematic Universe will interpret the Amazons as descendants of ancient Kryptonians; you can speculate on that in the comments below.

Finally, Jett believes we'll get our first look at Ben Affleck as Batman "really soon." He expects Warner Bros. to release an early publicity still shortly after filming begins, "to lessen the blow of bootleg set spy-pics," ala Sony's strategy with The Amazing Spider-Man 2.

Once again, take all of that as rumor until proven otherwise. With production set to begin soon, many of our questions will be answered in the coming weeks and months — including, hopefully, an official title, so we can stop calling it "the untitled Man of Steel sequel" already.

Also starring Henry Cavill, Gal Gadot and Amy Adams, the untitled Man of Steel sequel flies into theaters on July 17, 2015.

Update: Jett has written a follow-up on Facebook that states, in part, "In the recent mailbag I did with you all, I speculated on how Goyer/Snyder *might* account for the origins of the Amazons: Decedents of ancient Kryptonian astronauts who were able to create an all-female race due to Kryptonians artificially creating their offspring. It was nothing but a guess -- pure speculation and my opinion -- and nothing more. Now, many outlets have picked up the 'story' and have run it as either me claiming it to be fact or me claiming it's 'inside info/rumor.' BULLSH*T! I get that people are anxious for BvS news, but this was ridiculous! One dude on one badass outlet went on a tirade/rant over the whole thing which pretty much amounted to an online meltdown directed towards WB."
