<P> Select footage from the film was screened around various cities during the film's press tour in early April, ahead of the film's Los Angeles premiere . The Russos noted that only a limited amount of the film would be shown at these screenings to reduce the chance of spoilers being leaked . Adam Chitwood of Collider commented that this was "highly unusual as most Marvel movies are screened in their entirety for press about a month before they hit theaters". Ahead of the United States release, AMC Theatres in New York City and Orlando, Florida aired an eleven - MCU film marathon beginning on April 25, leading to a screening of Infinity War . The El Capitan Theatre in Los Angeles also had a similar marathon ahead of the film's release . </P> <P> In May 2017, Robert Downey Jr. and his philanthropic organization Random Act Funding partnered with Omaze to initiate a contest to benefit the organization . A randomly chosen winner from those that donated would receive an Infinity War set visit . A life - sized statue of Thanos, created by Legacy Effects, was on display at D23 Expo 2017, alongside statues of the Black Order / "Children of Thanos": Corvus Glaive, Proxima Midnight, Ebony Maw, and Cull Obsidian . Additionally, Feige, Joe Russo, Downey, Brolin, Bettany, Olsen, Klementieff, Gillan, Bautista, Cheadle, Mackie, Cumberbatch, Stan, Holland, Boseman, Ruffalo and Hemsworth appeared at D23 Expo to present a clip highlighting the 10 years of MCU films, along with footage from Infinity War . The footage, which was screened exclusively for the panel, received strong audience reaction, with fans "literally on their feet and jumping as the footage played". Julia Alexander of Polygon commented, "to say that there was quite a bit happening in the trailer would be one hell of an understatement, but that's not what got me excited about the promises Infinity War may deliver upon . Seeing Spider - Man in the same movie as Iron Man, Thor, Star - Lord and the Scarlet Witch finally feels like Marvel has made the movie it always wanted to--and the one we've always wanted to see . For nearly ten years we dreamt of this reality and to see it play across a massive screen...it was impossible to not feel emotional ." CinemaBlend's Eric Eisenberg said the footage left him "literally shaking", with the film looking "like it could be one of the most epic blockbusters ever created", concluding "the hype (for the film) most definitely feels very, very real". Haleigh Foutch for Collider said, "It looks dark and dramatic, and utterly epic . It's clear Marvel is trying to do something different here...to pay off a decade's worth of narrative and world - building . While it's impossible to tell from two minutes work of footage, it certainly looks like that gamble paid off ." The D23 footage was also shown at the 2017 San Diego Comic - Con International . Due to the two convention presentations, Avengers: Infinity War generated over 90,000 new conversations on social media from July 17 to 23, the third-most during that time period behind Thor: Ragnarok and Justice League, according to comScore and its PreAct service . Infinity War stayed in third the following week, with over 41,000 new social media conversations, behind Ragnarok and It . By the week of October 16, Infinity War had generated over 679,000 total social media conversations . </P> <P> To promote the release of the film's first trailer, Marvel released "a retrospective video looking back at some of its best trailers" since Iron Man, "paired with fan reaction videos to those trailers". The first trailer for Avengers: Infinity War debuted on Good Morning America on November 29, 2017 . Josh Spiegel of The Hollywood Reporter said, "The trailer promises, in many ways, exactly what anyone with a passing familiarity with superhero movies would expect ..." but "the most important part of the trailer is how it carefully, deliberately introduces the notion that the Infinity War films are going to function as a passing of the torch, from one set of Avengers to a newer group ." Scott Mendelson writing, for Forbes, noted that even though the trailer was not much different from the convention footage screened earlier in the year, it was "damn impressive . Moreover, it uses Nick Fury's big' Avengers Initiative' speech, along with Alan Silvestri's Avengers theme, to excellent effect ." Conversely to Mendelson, Alexander commented on the different marketing strategy for the film between the convention footage scenes and the trailer scenes, feeling the "two couldn't be more different". She noted how the convention footage ("meant to please a crowd running on little sleep and jittery with anticipation") was released between Guardians of the Galaxy Vol. 2 and Thor: Ragnarok, and "(i) t made sense to use Thor and the Guardians to hype up (Infinity War)" because "Marvel relied on the anticipation of Thor: Ragnarok and Guardians of the Galaxy Vol. 2's success to excite fans, and footage of older movies set to classic Marvel scores as a way to drive home how this movie is an event in itself ." Conversely, the trailer ("designed to explain what's about to happen, teasing it out with additional background") heavily featured Black Panther and Wakanda, which Alexander said could not have been done earlier, without the additional marketing for Black Panther that happened after the conventions to provide additional context . Gael Cooper of CNET observed that the trailer was viewed nearly 500,000 times in its first 15 minutes after it was posted on YouTube, but questioned if the trailer broke the site after the view counter appeared to be stuck at 467,331 . The trailer was viewed 230 million times in its first 24 hours, becoming the most viewed trailer in that time period, surpassing the record of It . </P> <P> In January 2018, Marvel Comics published a two - issue prequel comic titled Avengers: Infinity War Prelude, which serves as a bridge between Captain America: Civil War and Avengers: Infinity War . A commercial for Infinity War aired during Super Bowl LII . The ad generated the most social media buzz out of all the films advertised during the Super Bowl, according to comScore and United Talent Agency; it was viewed 17.6 million times across YouTube and Facebook . On February 27, 2018, Disney and Marvel announced the Marvel: The Universe Unites charity campaign leading to the release of merchandise for the film on March 3 . The week - long event saw stars from the film create social media challenges to provide funds and raise awareness for charities that support children and families impacted by serious illness . If their collective posts reached 1 million likes, Marvel said they would make a $250,000 donation to Starlight Children's Foundation . Additionally, Disney planned to donate 10% of sales of all Marvel products purchased at Disney Stores in the United States and online on the weekend of March 3 to the Make - A-Wish Foundation, up to $50,000 . Hasbro donated $1 million worth of cash and products to Give Kids the World Village and Funko made a $1 million toy donation to Starlight . </P>
