According to Tom Holland, who starred as Peter Parker/Spider-Man in both 2017's Spider-Man: Homecoming and its 2019 sequel Spider-Man: Far From Home, the third installment will likely finish production February 2021.
A video shared on Reddit, which was first posted on Holland's father's Patreon account, showed the actor speaking about Spider-Man 3 and his other upcoming film, Uncharted. Holland mentioned Spider-Man 3 would complete filming in February of next year, following production ending on Uncharted. However, Marvel Studios hasn't yet given an official confirmation about Spider-Man 3's planned wrap date.
The third Marvel Cinematic Universe Spider-Man film will follow last year's hit, Spider-Man: Far From Home, which showed the web-head adventuring through Europe. The film ended with Jake Gyllenhaal's villain Mysterio revealing Spider-Man's true identity, which will likely play a big part in Spider-Man 3.
Not much has been revealed about the plot for Spider-Man 3, though several actors from previous MCU Spider-Man films will reprise their roles, including Zendaya as Michelle Jones/MJ and Marisa Tomei as Aunt May. Additionally, J.K. Simmons, who also played the role of J. Jonah Jameson in Sam Raimi's Spider-Man trilogy, has already filmed another scene as the character. However, it's uncertain in which MCU project Simmons' next appearance will occur.
Starring Tom Holland and Zendaya, the third MCU Spider-Man film is set for release on Nov. 5, 2021. An official title for Spider-Man 3 has not yet been announced.
