Batman V Superman: Dawn of Justice has finally hit theaters, and is enjoying a fairly strong performance on its opening weekend despite some disappointing reviews. Love it or hate it, a lot of work went into developing the world of Batman V Superman. To give his fans a glimpse into the film's production, concept artist Victor Martinez (who has done concept work on films such as Terminator Genisys, Tomorrowland, and Avatar) recently revealed some of the work he did on BvS.

Posting to Facebook, Martinez shared five concept pieces that he produced for the film. The post accompanying the concept art mentioned how much fun he had working on the project, and praised the film's production designer and crew. His full message read as follows:

"Had a lot of fun working on Batman v Superman: Dawn of Justice. Great job by Production Designer Patrick Tatopoulos creating a visually stunning world for this film, and all the crew who brought it to life! Here are some images of artwork I created to help realize that vision. Enjoy!"

One of the most striking pieces in the work that Martinez posted was the piece that showed Batman and Superman facing off. His post also included a dramatic shot of Batman, and even early concepts of a certain memorial in Metropolis. There were no concept pieces released that showed Wonder Woman, Lex Luthor, or Doomsday, so it's unknown if Martinez merely picked a few favorite pieces or if he simply didn't work on art that included those characters.

It's always interesting to see how film visions change between the concept stage and when they actually make it on the screen. Some movies stay pretty close to the concept art, while others evolve significantly. When several different versions of a concept are developed before elements hit the screen, it's nice to be able to look at the earlier versions and either see how things evolved or wonder what the filmmakers were thinking when they changed a design that worked better than what they went with.

In the end, seeing some of the concept art for Batman V Superman isn't going to change anyone's opinion of the film. It might give some fans a better idea of what went into the making of the movie, though, and a glimpse of how the filmmakers envisioned the movie early on.
