Quick Take:

COVID-19’s Delta variant is causing problems for a film industry that is trying to work at full speed. A number of TV shows and movies have had outbreaks, including 12 cases linked to the set of Fox’s “The Masked Singer.”

Hollywood’s strict safety protocols are being tested as the COVID-19 Delta variant rips through Los Angeles.

Several TV and film productions have reported virus outbreaks and some have been forced to pause shoots, even as the industry grapples with new safety protocols. Fox’s “The Masked Singer,” CBS’ “S.W.A.T” and the HBO Max movie “House Party” are among those listed as having active outbreaks with three or more laboratory-confirmed COVID-19 cases, according to L.A. County

Fox’s popular singing show has 12 cases, the largest number among the listed productions at the Red Studios Hollywood set, although work wasn’t been halted. Insider first reported the outbreak.

“The safety of the entire cast and crew has been and will continue to be our number one priority,” Fox Entertainment said in an emailed statement. “We work closely with local and state officials and the unions to ensure we have the safest environment possible.”

“S.W.A.T” had five cases but the show didn’t need to pause production, while the movie “House Party” reported nine, including infections confirmed in pre-employment testing, a person with knowledge of the production said on condition of anonymity. The production has resumed after pausing for a few days. NBC Universal’s post-production office has reported four cases.

Nonetheless, filming on location in Los Angeles has continued to rise. Last week, the number of shoot days rose to 620 from 566 the previous week, a 9.5% increase, according to data from Film L.A, the nonprofit that organizes filming permits for the county. The volume of on-location production is beyond 2019 filming levels, when 600 shoot days were registered during the same period.

The outbreaks illustrate the effect the new Delta variant is having on one of Southern California’s most vital industries. The film business has largely been able to continue working throughout the pandemic since it restarted in June. The industry agreed that safety protocols on masking and testing have helped stem outbreaks on film sets. The latest infections have yet to reach the levels seen during the winter, when unions and health officials warned the industry to pause as so not to strain hospitals.

Last month, the Alliance of Motion Picture and Television Producers, which includes Netflix, Walt Disney, Amazon and other studios, agreed to new safety protocols for filming during the pandemic. The agreement with the industry’s leading unions, including the Directors Guild of America, SAG-AFTRA and the Teamsters Hollywood local, allows vaccinations to be mandated among certain members of the cast and crew on a production-by-production basis. The new terms allow for a loosening of safety protocols on masking and testing that can be tightened up if infections rise beyond certain triggers.

Some companies, such as Disney, have announced vaccination mandates. Netflix has told producers to require vaccinations on all its U.S. productions. However, for the studios that agreed to last month’s new protocols, workers can be exempt if they can provide verification that they have a disability or sincerely held religious beliefs that prevent them from being vaccinated.

The Writers Guild of America has also recommended its members get vaccinated before gathering to work on productions.
