<P> In October 2014, Marvel announced a two - part sequel to Avengers: Age of Ultron, titled Avengers: Infinity War . Part 1 was scheduled to be released on May 4, 2018, with Part 2 scheduled for May 3, 2019 . In April 2015, Marvel announced that Anthony and Joe Russo would direct both parts of Avengers: Infinity War, with back - to - back filming expected to begin in 2016 . The same month, Kevin Feige said that the Infinity War films would be two distinct films "because they (have) such shared elements, it felt appropriate...to (subtitle the films) like that . But I wouldn't call it one story that's cut in half . I would say it's going to be two distinct movies ." By May 2015, Christopher Markus and Stephen McFeely had signed on to write the screenplays for both parts of the film, which draws inspiration from Jim Starlin's 1991 "The Infinity Gauntlet" comic and Jonathan Hickman's 2013 "Infinity" comic . Anthony Russo added the film was inspired by 1990s heist films, with Thanos "on a smash - and - grab (to acquire the Infinity Stones), and everybody's trying to catch up the whole movie ." In May 2016, the Russos revealed that they would retitle the two films, to further remove the misconception that they were one large film split in two, with Joe stating, "The intention is we will change (the titles), we just haven't come up with (them) yet ." That July, Marvel revealed the film's title would be shortened to simply Avengers: Infinity War . </P> <P> Principal photography began on January 23, 2017, under the working title Mary Lou, at Pinewood Atlanta Studios in Fayette County, Georgia, with Trent Opaloch as director of photography . In early February, Marvel confirmed the involvement of Robert Downey Jr. as Tony Stark / Iron Man, Chris Pratt as Peter Quill / Star - Lord, and Tom Holland as Peter Parker / Spider - Man in the film . Additional filming took place in Scotland beginning in February 2017 . The filming occurred in Edinburgh, Glasgow and the Scottish Highlands, with studio work taking place at Wardpark Studios in Cumbernauld . Filming also began at Durham Cathedral in Durham, England in early May 2017 . In late June 2017, filming occurred in Downtown Atlanta, as well as Atlanta's Central Park in early July, before moving to Queens, New York in the middle of the month . Filming concluded on July 14, 2017 . For the film's final scene, where Thanos emerges healed in a nipa hut, the filmmakers partnered with Indochina Productions, a studio based in Thailand, to acquire footage of the Banaue Rice Terraces at Ifugao, Philippines . </P> <P> Later in July 2017, Joe Russo stated there were a couple of unfinished scenes for Infinity War that would be shot "in the next few months". In early March 2018, Disney moved the release of Infinity War in the United States to April 27, 2018, to have it be released the same weekend as some of its international markets . Visual effects for the film were created by Industrial Light & Magic, Framestore, Method Studios, Weta Digital, Double Negative, Cinesite, Digital Domain, Rise, Lola VFX, and Perception . With an estimated budget in the range of $316--400 million, it is one of the most expensive films ever made . </P> <P> In June 2016, Alan Silvestri, who composed the score for The Avengers, was revealed to be returning to score both Infinity War and its sequel . Silvestri started to record his score in January 2018, and concluded in late March . Silvestri felt working on the film "was a really different experience than anything I'd done before, especially in regard to the approach and balancing quick shifts in tone ." Ludwig Göransson's theme from Black Panther is also used in the film . Hollywood Records and Marvel Music released the soundtrack album digitally on April 27, 2018, with a release on physical formats following on May 18 . Two versions were released, a regular and deluxe edition, with the deluxe edition featuring some extended and additional tracks . </P>
