The one-off special was due to have been filmed next week on the original sound stage in Burbank, California, according to the source, and broadcast in May on the upcoming HBO Max streaming service.

But movie and TV production in Hollywood has come to a halt in the past week due to restrictions brought in to contain the spread of the coronavirus in the United States. No new date has been set for filming the special.

HBO Max declined to comment.

The long-awaited unscripted show, featuring all six “Friends” stars Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer, was to have been a big draw for the planned HBO Max streaming service.

The hit comedy series ended in 2004 but found a new lease of life on Netflix where it was the second most-watched show in 2018.

HBO Max last year secured the rights to all 10 seasons of “Friends” for its streaming service and the comedy series is no longer available on Netflix.

The source on Wednesday said that HBO MAX still intended to launch as planned in May. An exact date has still to be announced.

The Friends delay follows the suspension of filming of all Netflix, Disney and Universal Pictures live action movies, including Mission: Impossible 7 and The Matrix 4, as well as television shows ranging from Saturday Night Live to The Amazing Race.
