A new teaser for "Batman v Superman: Dawn of Justice" shows no love lost between the Man of Steel and the Dark Knight.
In the clip, Superman appears to be in charge of a Gitmo-like detention facility where soldiers kneel in deference to him as he enters -- and Batman is one of the prisoners being held in chains.
Check it out in the clip above.
It's not clear why the two superheroes are fighting, but a synopsis released in early November offers some hints.
The teaser will lead to a full trailer that will be broadcast on Wednesday night during "Jimmy Kimmel Live."
