An electrical transformer fire at the Warner Bros. Studios lot early Friday afternoon briefly cast black smoke over the Burbank area.
The fire was contained to the area of the transformer and knocked down a few minutes after it started. No studio buildings were damaged by flames, the fire department said.
Crews responded to at least one report of people trapped in an elevator on the studio lot, where some power was apparently out due to the transformer fire, City News Service reported.
There were no reports of injuries, according to the Los Angeles County Fire Department.
