Officials say a large fire is burning on a lot at Universal Studios.
Los Angeles fire Capt. Frank Reynoso says the blaze was reported just before dawn Sunday on a sound stage on a back lot. He says filming could have been going on at the time.
About 100 city and county firefighters are helping studio firefighters tackle the blaze.
Reynoso says there has been at least one explosion but the fire is contained to the back lot. Firefighters are working to ensure the flames don't spread to nearby brush.
There are no reports of any injuries.
It is currently a Three Alarm Fire.
