Avengers: Endgame is destroying box office records, earning over a billion dollars in the first week alone. Now a week out from the film's global release, the newest Marvel Cinematic Universe is set to break one of the biggest box office records of all time.

Bloomberg reports analysts estimate Avengers: Endgame could beat Avatar and become the highest-grossing film ever. Endgame has earned $1.91 billion, making it the fifth most successful film of all time.

Avatar earned over $2.7 billion at the global box office in 2009, making an estimated $600 million more than the second highest-grossing film of all time, Titanic. Both films were written and directed by James Cameron. The financial publication expects Endgame to surpass Avatar within the next few weeks.

However, there's a chance the upcoming Avatar 2 and Avatar 3 could repeat the success of the prior film in the series. Avatar 2 is set to premiere Dec. 18, 2020, and Avatar 3 on Dec. 17, 2021.
