Deadline reports that the Walt Disney Company is "adamant" that it won't be moving May 1's Black Widow despite growing concerns about Coronavirus (COVID-19).
The Hollywood trade reports that rumors are rampant "in the distribution sphere" that Black Widow would be re-located to November 6, taking over the date from Eternals - which would in turn move that ensemble film to 2021. That's not Disney's plan "at hand" according to Deadline however, and cites conversations between Disney and theater owners that they're "staying the course within their current slate."
Earlier this week, MGM/Universal decided to move April's James Bond: No Time To Die back seven months "after careful consideration and thorough evaluation of the global theatrical marketplace."
In January, China closed all of its 70,000 movie theaters after the outbreak of COVID-19 according to The Hollywood Reporter.
