Marvel Cinematic Universe Fans Celebrate the 12th Anniversary of Iron Man

This has been a big week for Marvel Cinematic Universe anniversaries! Yesterday marked five years since Avengers: Age of Ultron officially hit theaters, and today is the 12th anniversary of the worldwide release of Iron Man, the move that started it all. Many people have taken to the Internet to celebrate this important date, which has served as a nice distraction. Marvel fans have been especially bummed this weekend because it was supposed to see the release of Black Widow. Taking the date once held by The Eternals, Disney will now open the Cate Shortland-directed Black Widow on November 6, 2020, as most theaters around the world remain shuttered indefinitely due to concerns over COVID-19. The film's opening night Thursday also would have marked the official start of Phase 4 of the Marvel Cinematic Universe. Thankfully, there are over 20 films for fans to enjoy while they await the upcoming movies.

"Iron Man released 12 years ago today," @lord0fthunder tweeted this morning. You can check out the tweet below:
