The film is rumoured to get a one-time premiere at Coachella.
Cryptic ads on Spotify last week teased the release date as April 13, the night after Gambino, real name Donald Glover, is headlining the festival.
However, Glover has now confirmed that it’ll arrive on Amazon Prime at 12am PST on Saturday.
He says that the project is a “tropical thriller” and released a brief trailer that sees him starring alongside Rihanna.
“On Guava Island, a local musician is determined to throw a festival for everyone to enjoy,” reads the film’s description.
It was written by Glover’s brother Stephen, and was reportedly inspired by classic films such as City of God and Purple Rain. It’s directed by Glover’s “Atlanta” collaborator Hiro Murai and lso stars Black Panther’s Letitia Wright.
Last year the artists were spotted filming together in Havana, Cuba, but further details of exactly what it is are yet to emerge.
Gambino screened a trailer of the project during his PHAROS Festival in New Zealand in November last year, where one viewer managed to capture it.
This comes after some fans speculated that it is an action film. The story entry on IMDB reads “A tropical thriller that casts Donald Glover as a musician with designs on pulling off a scheme to rob his way into the good life, which quickly gets him in over his head.”
However others think a visual album might go alongside what could be his last album release later this year.
The résumé section on cinematographer Christian Sprenger’s site reportedly credited him as a Director of Photography on Guava, with the entry including the note “Visual album ft. Donald Glover (aka “Childish Gambino”)”.
This has yet to verified by either Rihanna or Glover’s representatives, however, and the entry appears to have been removed.
Although premiering on Amazon, it’s expected to appear on the Coachella Livestream too.
For the ninth year running, music fans can watch Coachella from the comfort of their own home on multiple devices, and for the first time ever, will be able to watch the second weekend too.
Confirmed live stream artists include Billie Eilish, Janelle Monáe, The 1975 and Wiz Khalifa. You can find the full list of artists who are being live-streamed on the Coachella YouTube, which continues to be updated.
There will be a choice of three live stream feeds with different artists performing simultaneously, and personalised viewing schedules can be created and live stream channels will automatically change to artists selected by fans.
Highlights from the weekend will be available through a video-on-demand hub, with co-hosts Nadeska Alexis, Valerie Lee, and special guests to bring fans interviews with artists and creators from throughout the festival.
Performances times are due to be released this week, and you can find out exactly how to watch the festival here.
Coachella is being held over two weekends this April (12-14 and 19-21).
