Police also found several ignition sources, all signs that detectives said could point to an act of terrorism.
Detectives said the man was very cooperative with studio security but they must take situations like these seriously where possible terrorism is involved. Authorities were still struggling to answer questions about what the man wanted to do on the studio lot.
"Anytime you have someone who trespasses on a studio lot there's a couple things that could come up, whether they want to look for a particular actor or actress or have a script they want to deliver," said Lt. John Diibert, Burbank Police Department.
The driver faces several charges, including possession of a destructive device. He was being held on $500,000 bail.
