with a large-scale simulated wave, which was integrated with a combination of day-for-night footage, blue screen shots for the actors in truck interiors, a truck on a rotisserie rig, an interior cabin in a water tank, and VFX simulations for debris. For creating the lighthouse, a full-size house with the base of the lighthouse tower was constructed by the FX team. Additional house and dock sets were built on sound stages. A digital build-out was done to complete the lighthouse tower and extend the dock fully out into the sea. For the sequence where the camera pushes into a toy snow globe with a tiny lighthouse inside, a CGI transition was created from the lighthouse's living room set to a fully CGI winter coastline. For creating the Trench creatures, motion capture was done on set by stunt performers. Music On March 7, 2018, Rupert Gregson-Williams was announced as the composer for Aquaman. Gregson-Williams previously wrote the score for Wonder Woman, the fourth film in the DC Extended Universe. The soundtrack was released by WaterTower Music on December 14, 2018. The album features an original song by American musician Skylar Grey titled "Everything I Need", written by Grey and Elliott Taylor. Joseph Bishara, Wan's frequent collaborator, composed a piece called "Trench Engaged" for the trench sequence. Marketing In March 2017, prior to filming, a first look at Aquaman was shown during CinemaCon in Las Vegas, Nevada, with Momoa introducing a video of director James Wan displaying a concept art sizzle reel. Later, on July 22, the film's footage made its debut at San Diego Comic-Con (SDCC) 2017 with a teaser presented by Momoa during the Warner Bros. panel; director Wan presented the footage, stating that "in a lot of ways, this is an origin story," In April 2018, another teaser, with new footage, was shown by Wan and Momoa at CinemaCon, joined by Amber Heard, Patrick Wilson and Yahya Abdul-Mateen II on stage. Wan teased the conflict between Arthur and Ocean Master, stating that "it's almost a very classic Shakespearean story about brother from another world vs. brother from another world. And it really is a classic story of sibling rivalry." On June 11, 2018, the film's first trailer was previewed at CineEurope. On July 21, 2018, the first trailer was released at SDCC 2018, considered the best received trailer; it was later attached to theatrical showings of Teen Titans Go!
