Earlier this week it was reported that the name of the fourth Avengers movie won’t be revealed until after Avengers: Infinity War is released next year. However, Guardians of the Galaxy star Zoe Saldana may have let slip a potential title for the movie.

During an interview to promote Guardians of the Galaxy Vol. 2, Saldana said that she had finished her scenes for Infinity War, and would return to shoot something she referred to as Gauntlet later in the year. Check out the video below:

Guardians director James Gunn was quick to downplay Saldana’s apparent slip, telling Yahoo writer Tom Butler that she “misspoke.” Marvel boss Kevin Feige previously suggested that the title of Avengers 4 would be a spoiler for the events of Infinity War.

The Infinity Gauntlet was the title of a Marvel comic book crossover event that ran in 1991. It saw the evil Thanos battle many of Marvel’s greatest heroes using the power of the Infinity Stones embedded in the ornate glove of the title.

Infinity War is currently in production. The movie was originally set to be released in two parts, shot back-to-back. However, Avengers 4 has since become a separate film, and last week it was confirmed that it wouldn’t enter production until after Infinity War wraps. Both movies will be directed by the Russo brothers, who helmed the last two Captain America films.

Feige recently suggested that the Marvel Cinematic Universe might go through some big changes after Avengers 4. “As we get to Infinity War there will be a sense of a climax,” he said. “By the time we’re at the untitled Avengers 4, 22 movies will have encompassed the first three phases of the MCU. And what happens after that will be very different. I don’t know if it’s Phase 4, it might be a new thing.”

Avengers: Infinity War hits theaters on May 4, 2018, while Avengers 4 is due on May 3, 2019. Guardians of the Galaxy Vol. 2 arrives next week.
