There's a good chance that Marvel Studios will delay Black Widow again due to the current status of the box office. Heading into 2020, the Marvel Cinematic Universe was set to begin a new era. The Infinity Saga concluded with Avengers: Endgame becoming the highest-grossing movie of all-time and Spider-Man: Far From Home became the biggest solo Spidey film ever. Despite Scarlett Johansson's Black Widow dying during the events of the former, she is still slated to finally get a solo film of her own.
Marvel Studios' plan has long been to use Black Widow to kick off Phase 4 of the MCU, but that has become more challenging than they ever could've predicted. The coronavirus pandemic shut down theaters across the world in March and eventually led to Black Widow losing its May 2020 release date. Marvel was forced to push the film to November 2020, a move that resulted in almost the entirety of Phase 4 shifting in some way. The six-month delay allowed for hope that Black Widow will be able to be released in theaters at this point as the first MCU Phase 4 movie. But, even that has recently started to look less likely.
Even though the majority of theaters are open, social distancing measures and the current state of the coronavirus pandemic have led to a tepid response. The fallout of recent events has only just begun. Many are now turning their eyes back to Black Widow to see what Disney and Marvel will do with the Phase 4 blockbuster. So far, they've stuck to a November 2020 release date for Black Widow in theaters, but all signs point to Johansson's solo movie having to wait even longer to debut.
