Here is a comprehensive summary of the Wikipedia article "2024 in film":
2024 proved to be a landmark year for cinema, celebrating significant anniversaries such as Columbia Pictures and Metro-Goldwyn-Mayer (MGM) reaching their 100th year, and the original Mickey Mouse films, including Steamboat Willie (1928), entering the public domain. The year's release schedule was notably shaped by the 2023 Hollywood labor disputes, including strikes by the Writers Guild of America and SAG-AFTRA, which led to many new films being postponed and popular classics like The Lion King (1994) and Alien (1979) being re-released.
Box office records were consistently broken, with Inside Out 2 becoming the highest-grossing animated film of all time and the fastest animated film to reach $1 billion worldwide. Not to be outdone, Deadpool & Wolverine shattered records as the highest-grossing R-rated film ever and achieved the biggest opening weekend for an R-rated title.
Further successes included Moana 2 and Despicable Me 4, the latter pushing its franchise to become the first animated series to gross $5 billion. The musical film adaptation Wicked also made history by setting new opening weekend records and becoming the highest-grossing Broadway musical film adaptation ever, contributing to a year rich with cinematic achievements and evolving industry dynamics.
