I guess this is the official, or pre-official, Batman x Superman movie thread, so I'll just repost what I shared earlier in the MoS thread concerning the Bats appearance in the MoS sequel:
I think folks should refrain from getting their hopes up about this Superman x Batman union in the MoS sequel. It'll likely just amount to an extended cameo by Bruce Wayne.
This is how I imagine it will play out:
Warning: Spoiler! (Click to show)
In the aftermath of Metropolis' destruction, we are witness to a city attempting to repair itself. Taking part in the rebuilding effort are several prominent citizens and home-grown companies, of which Lex Luthor and his Luther Corp. are a part of. Also in the mix is Wayne Enterprises, from neighboring Gotham City, whose billionaire CEO has pledged some undisclosed amount (speculated in the millions) to the "affected citizens" fund.
In proper fashion, a huge and ritzy gala is thrown in recognition of those people who've done the most for Metropolis during these trying times; and of course, as is always the case with such events, many of the attendees are shown to hail from the upper echelons of the social order, with nary a consideration/invite for the men and women actually involved in the rebuilding effort (see construction workers, reg. on duty cop, firefighters, nurses, etc). Simply stated, the gala is an ensemble of the rich, for the rich, to speculate and amuse themselves (who lost the most property, whose insurance policy paid out the most, etc).
Anyway, as it is customary to document these events for the hoi polloi, certain privileged members of the press are given access, and as we scan the room we stumble across Perry White and Lois Lane from the Daily Planet, naturally, and Clark Kent, quite unnaturally. Clark has been dragged there in lieu of a more seasoned journalist because Lois believes the event will hone his journalistic skills (throw him to the sharks and he'll have no choice but to learn how to swim). Also, having Clark there frees her from her journalistic obligations and allows her to cavort with the rich.
After a few overwhelming profiles, Clark retreats to the food spread at the back of the room to take a breather. There, he surveys the room full of people with pretentions unlike anything he has ever known. For a guy whose sensibilities were molded on a farm in smallville USA, the present milieu stands in stark contrast to everything he has known . He reflects on his once simple life; of humble and sincere folk; of close knit farm communities buoyed by generosity and selflessness. These bonds, he imagines to himself, are what life must be about. Not this (surveying the room yet again): superficial and self serving relationships held together only by money, power, and exploitation. A sad cold bunch, he considers to himself. His longing for home and reflections on the present are soon interrupted, however, by a sudden voice next to him. A voice that seemingly crept out the darkness like a phantom. Next to him stands a sharply dressed man, with a drink in one hand, and with the other hand tucked in his trouser pocket. Clark wonders to himself, "when and where did he come from"?
A man whose presence escapes detection by even the Man of Steel, remarkable, wouldn't you say?
The two begin to chatter. It's obvious to Clark that the fellow is cut from the same social cloth as many in the room. However, beneath the superficiality of wealth, there appears to be more to the fellow. A great deal more. Clark is mystified.
Their conversation is soon interrupted by the shriek of a microphone on the other side of the room. The room goes quite as all attention is directed towards the man holding the mic.
A man who was earlier introduced to Clark by Lois as Lex Luthor, "one of Metropolis' shining stars", is holding the mic. He makes a few opening remark, comments, jokes; the crowd laughs pleasantly. He then acknowledges some of the various esteemed invitees in attendance--there is applause. After the applause dies down, he starts addressing why they are all there. He talks about taking a stand, a need for action and a call to action to protect the world from a new kind of threat. He talks about the rampancy of chaos in the world; of mad terrorists hell bent on destroying cities, of aliens hell bent on destroying earth, etc. He talks about brave men and women standing for something; of heroes arising from the ranks of the ordinary to stand up for justice. He touches on the vigilante known as the Batman in Metropolis' sister city, Gotham. There is faint but recognizably haughty murmur in the room. He talks about the "good alien" who protected Metropolis when the "bad aliens" attacked. There is an ambivalent murmur in the room. Still, he continues: "these 'heroes' are outliers that cannot be counted on or be trusted when we most need them." He talks about taking matters into their own hands--there is approval in the audience. The need to take matters into their own hands, in conjunction with their visible defenselessness in the face of considerable threats, he explains, is the impetus behind his forthcoming revelation--a R&D partnership between his company, Luthor Corp. and Wayne Enterprises, with backing from the U.S military, aimed at shoring up Earth's defenses--on the micro and macro level--in the face of increasingly hostile forces. There is great approval in the room, then clapping.
Lex, looking satisfied, reveals that there is more to be said about the matter, and invites a special guest to join him: "Bruce Wayne, get out over here...."
There is restlessness in the gathering as everyone looks about them. From various pockets, the curiosity is audible: "Bruce Wayne, here...well isn't that something..."; "I heard he lost his fortune in some scandal involving the futures markets..."; "He never called me back after that night, I thought we really had something special...." The anxiety in the room is palpable. Even Clark, at this point, is wondering who this Bruce Wayne fellow is.
Lex scans the ball room, soon stopping and fixing his gaze at the back, to where Clark is standing: "ahh, there he is; Bruce Wayne you rascal, come on up here."
Everyone in the room follows Lex's gaze towards Clark. Clark looks back, like a deer in headlights, at all eyes seemingly peering at him.
The guy standing next to him, who he was briefly chatting up right before Lex's interruption, has set his drink down. The fellow looks at Clark with a mischievous smile about him, and states just how much he hates these things--pointing to Lex holding the mic. "Well, guess being the CEO can't be fun and games. Occasionally you have to do stuff like this; how's my tie by the way"? His tie is set and held sharply in place. Clark echoes, "looks great," still faintly perplexed but now approaching the shores of realization as to who this fellow is.
He thanks Clark and pats him on the shoulder, telling him that he is a decent fellow and that he has enjoyed talking to him. He begins walking toward Lex on the other side of the room. He walks calmly and confidently like a man who has rehearsed this many times before. Like he were an actor and this was all an act to him. "Bruce Wayne everyone...," Lex announces once more into the mic, with applause all around.
Clark looks at the frame of the man walking to the front, musing to himself, "Bruce Wayne..."
So yeah, that's my lil imaginative take on it.
Y'all gotta remember that these studios are trying to bank as much money from these movies as they can. WB & DC gain absolutely nothing by rushing these projects. Why would they give us the Batman x Superman movie we all want (WF or prequel to JL) so soon when they can build the hype exactly as they did at Comic Con and by alluding to it via other projects? Will we see it eventually, sure. But now, best believe they're just gonna try and eat good off the MoS franchise, the Batman franchise, Flash, etc.
They'll eventually, obviously, get to the legitimate JL movie, but not now or anytime soon. So as far as this Batman cameo in the MoS sequel, I think it'll more than likely be a Bruce Wayne extended cameo. I just don't see a suited up Bats teaming up and fighting side by side with Supes like what was implied.
Mark my words, it isn't going to be just a little cameo by Batman. Is it going to be a Superman film with Batman in it? Likely. Will Batman play a big role? Almost guaranteed. This isn't a TV show where a small cameo to tease Bruce Wayne will suffice. They are considering naming it Superman vs. Batman, no way they would put his name in there just to say Bruce called Clark Kent from Gotham.
