Following last fall's announcement that composers Hans Zimmer and Junkie XL were teaming up to score "Batman v Superman: Dawn of Justice," Junkie XL has issued a few glimpses at his research for the film on his personal Twitter account.

Zimmer and Junkie XL will craft separate themes, with Zimmer tackling Superman and Junkie XL taking on Batman. This won't be the their first collaborative effort; while Zimmer scored both 2013's "Man of Steel" and 2012's "The Dark Knight Rises," Junkie XL worked on both to provide additional music and rhythm design. The tweets below show Junkie XL prepping to score Batman's theme by catching up on the Dark Knight's cinematic history and 75 years of comic book lore.
