Filming for a show:

A bucket of what appeared to be black oil was thrown at actress Jennifer Anniston while filming the fourth season of the Apple TV+ production, The Morning Show, on a Manhattan set.

Images showed the actress getting covered in a black, thick substance thrown by an unknown assailant out of a paint bucket, while surrounded by people attending a protest, many of which also got splattered by the dark liquid.

Thankfully, no one was hurt in the incident as it turned out to be part of a scene the actress was filming for the show, in which her character, a fictional morning news program host named Alex, appears to be covering a social movement with her phone before being attacked.
