Marvel debuted early footage and concept art from the film at a press event in April 2017. Kyle Buchanan at Vulture.com praised the cinematography, costume and production design, and black cast, saying "Black Panther doesn't look like any of the other Marvel movies ... If this is what the future of superhero movies looks like, deal me in."[103] The screened footage was the first time Marvel had shown raw dailies, which Feige said they did to show off the "highest-class cast we've had" despite editing having not yet begun.[170] A poster was released ahead of the first teaser trailer, which premiered during Game 4 of the 2017 NBA Finals.[171][172] Fans on Twitter felt the poster was poorly photoshopped,[173] and it was compared to a real-life picture of Black Panther Party co-founder Huey P. Newton.[171] The trailer received a much more positive response, with Peter Sciretta of /Film finding it unexpected and refreshing,[174] io9's Charles Pulliam-Moore calling it "every bit as intense as you were hoping it would be",[175] and Andrew Husband for Uproxx feeling the single teaser outshone the entire Homecoming marketing campaign.[172] It was viewed 89 million times in 24 hours, generating 349,000 mentions (second only to the amount the Star Wars: The Last Jedi (2017) teaser received) and "dominated the conversation on social media" over Game 4.[176][173] Per comScore and its PreAct service, the film was the subject of the most new social media conversations for the rest of the week,[177] and the second-most for the week ending June 18, behind Homecoming.[178]
