Say what you will about Batman v Superman: Dawn of Justice, but the special effects were undeniably impressive. In an interview with Art of VFX, MPC's Guillaume Rocheron has shed some light on what it was like to work on the movie (his team's main focus was on the battle between Batman and Superman, and the later fight featuring The Trinity and Doomsday). He also shared some behind the scenes images focusing on the before and after shots of key scenes which were enhanced with special effects in the post production process. The full interview can be found by clicking on the link at the bottom of the page, but below is an excerpt along with the full gallery of stills from the movie.
"This movie and universe are grounded in the real world, so Zack captured as much as possible practically, probably more than he ever did before. There were a lot of sets, stunts, locations and practical effects. In order to create the largest possible canvas, Zack shot on both 35mm film and IMAX, for some of the key sequences. It was an exciting opportunity to create such iconic imagery on the best large format available. Zack is very well versed in VFX and his relationship with his long term visual effects supervisor, DJ Desjardin, allowed him to trust and embrace the process. After all, this is Batman v Superman so VFX plays a central role in telling the story of these characters."
