<P> Four days later, on Valentine's Day, the Facebook campaign was continued, with Marvel creating a "faux - status update" for Captain America, showing his relationship status had changed to "In a Complicated Relationship with Iron Man". At The Walt Disney Company's annual shareholder meeting in the Auditorium Theatre in March, CEO Bob Iger presented a clip from the film to "generous applause". From March 7 to March 10, Marvel released individual posters for characters in the film, continued its Facebook campaign with two teaser videos showcasing the participants on "Team Cap" and "Team Iron Man", and released a second trailer . The trailer was viewed close to 95 million times within the first 24 hours of release, surpassing the views achieved by the first trailer . In addition, 240,000 social media posts across Twitter, Tumblr, Instagram, and Facebook, among others, were made related to the trailer, surpassing the 81,000 the Age of Ultron trailer received in 2014 . According to internet analytics firm ZEFR, the trailer was viewed over 62 million times from YouTube and Facebook over four days, making it the second most viewed trailer at the time, behind the 64.6 million views for the first Star Wars: The Force Awakens trailer . It also became the top trailer in 2016 through March 13, 2016, according to research firm ListenFirst, for receiving the most likes, retweets and other engagement on Twitter . The trailer continued to be the top viewed trailer on YouTube and Facebook for three straight weeks according to ZEFR, receiving more than 96 million total views since its release . </P> <P> Mendelson called the trailer "a textbook case for unnecessary second pitches...Is there anyone out there who watched that first teaser back in December and said' Hmm, it looks good and all, but I need more evidence'?" He added that he was "a little disappointed by the big Spider - Man reveal," having previously wondered, after a Spider - Man character poster was not released with the others, if Marvel would have the "courage" to not include the character in any marketing materials before the film's release, letting the "Peter Parker scenes the film has to offer be something that is a surprise for theatrical moviegoers and / or something that drives post-opening weekend buzz". Mendelson's colleague at Forbes Mark Hughes felt differently, noting that the trailer was targeting the general audience rather than just fans by giving "us more explanation (and context) of why a clearly major battle is raging between Captain America and Iron Man", and by including Spider - Man since "there are plenty of surprises in these movies, and since we all already know Spider - Man is in Civil War, refusing to let us see him would frankly be a bit weird and pointless...it's common for average filmgoers to hear some final bit of information or see some final image and feel compelled, inspired, or otherwise driven to go out to the movies that day . There are any number of factors that can come into play...and the world needed to see (Spider - Man) because it's the sort of value - added element that can make (a) difference". Graeme McMillan of The Hollywood Reporter felt that the Spider - Man reveal "alone makes the trailer", describing it as feeling "like the comic book character come to life . That awkward, voice - cracking,' hey everyone' was as humble, playing - it - cool and cocky as he should be ." </P> <P> With the film seemingly continuing plot threads first introduced in Age of Ultron, Mendelson wondered "to what extent the whole' Consequences galore!' narrative of Civil War will improve Age of Ultron . As much great stuff as that movie has...(it ultimately shows) the main hero foolishly / recklessly (bring) a world - killing threat to Earth and lots of really bad stuff goes down and yet no one seems to care at the end...What does it mean if Civil War does retroactively improve Age of Ultron? Will we be at a point where we really can't judge a franchise installment on its own merits because a future installment may well fix the flaws a couple years down the line?" McMillan continued some of Mendelson's thinking, feeling that Marvel was "in an awkward place with Civil War" regarding superhero destruction moving forward . He wondered how superhero oversight would "actually prevent the kind of destruction that it's meant to stop...unless the bad guys all agree to play by the new rules" as well . "Worse still...the destruction caused by superhero fights (should now be) foremost in viewers' heads...the audience won't be able to enjoy the sight of the Hulk smashing a random minion through a wall without thinking of the property damage and / or whoever was standing on the other side of that wall . After Civil War, can Marvel go back to pretending that everyone is okay after any large scale event ever again?" </P> <P> Also in March, Marvel, in partnership with the National Academy of Sciences Science & Entertainment Exchange, Dolby Laboratories, Broadcom, and Synchrony Bank, announced the "Girls Reforming the Future Challenge", aimed at females aged 15 through 18 in STEM (Science, Technology, Engineering, and Mathematics education) fields, to submit projects they feel can change the world and have far - reaching effects . Five winners would attend the world premiere at the Dolby Theatre, and receive a tour of Walt Disney Studios and a $500 saving account from Synchrony Bank, with one grand prize winner receiving an internship at Marvel Studios . On April 10, Evans debuted an exclusive clip of the film during the 2016 MTV Movie Awards . Throughout the month, the Russo brothers and the cast promoted the film in Paris, Beijing, Singapore, Berlin and London . At the end of the month, Marvel released additional viral marketing videos of WHIH Newsfront, featuring Bibb once again reprising her role as Everhart . In the program, Everhart discusses with "political analyst" Will Adams, portrayed by Al Madrigal, the cost the Avengers bring for saving the world, and if they should have regulation from the government . Additional Newsfront segments saw William Sadler reprise his role as President Matthew Ellis, including an "exclusive" interview and his reaction to the incident involving the Avengers in Lagos . On May 2, 2016, Evans, Renner, and executives from Marvel rang the opening bell of the New York Stock Exchange in honor of the film's theatrical release . </P>
