Multiple sources are now reporting that Katherine Langford, the star of “13 Reasons Why” on Netflix, has joined the upcoming “Avengers 4” project at Marvel. The studio is staying quiet for now, though TheWrap was the first to announce the casting. Langford was a fan favorite in Netflix’s “13 Reasons Why,” though she only remained on the series for two seasons. Her short time on the series was enough to grab Langford a Golden Globe nomination and now it seems a spot in the Marvel Cinematic Universe.

Fans have been hitting Marvel’s social-media accounts over the past few weeks, hoping to get Marvel to announce the title of the next installment. The Russo brothers, which consist of Anthony Russo and Joe Russo, are directing the new film and have been teasing fans, but the duo haven’t officially announced anything. One of the leading fan theories is that the movie will be called “Avengers: End Game,” a phrase that was mentioned by Doctor Strange in “Avengers: Infinity War”.

“Avengers: Infinity War” was the latest installment to the long-running Marvel franchise, the film had a $257M domestic opening back in April. The movie went on to make over $678M in theaters and over $2B worldwide. “Avengers: Infinity” crushed the box-office the moment it came out, beating “The Avengers” which had the highest-grossing opening in the Marvel Universe with $207M. We should mention that “Black Panther” was close-behind with its $202M debut. One of the least popular installments, “Avengers: Age of Ultron,” still made $191M on its opening weekend, while “Captain America: Civil War” grossed over $179M on its debut.

The next big Marvel movie on the schedule is the highly anticipated film “Captain Marvel” from directors Anna Boden and Ryan Fleck. The film stars Brie Larson as the titular character, along with Mckenna Grace, Gemma Chan, Jude Law, Samuel L. Jackson, Clark Greg, and Annette Bening.

“13 Reasons Why” is set to return to Netflix in 2019, while “Avengers 4” is expected to launch in theaters on May 3, 2019.
