The star was escorted out of the Burbank Airport Marriott Hotel. Organizers claim he left the event early on Saturday after complaining the line at his table was too short. He returned late on Sunday, but was accused of becoming unruly.
Promoters claim he caused a disruption when he began signing autographs in the parking lot.
"We said, 'You've got to sit down. You can't malign us at our show. We're trying to accommodate you,' and he got ridiculous and threatened us again," said Kevin Martin, co-owner of Hollywood Show.
Part of the incident was caught on tape. Blake says to the camera, "I'm giving away free pictures to my fans because yesterday I embarrassed myself by behaving like a fool, so I came back today to be a good guy and give them pictures and give them autographs because they kept me alive for 70 years."
Blake was also seen on camera saying, "Call the police. There are deputies right there. There are cops all around."
Eventually, Blake left in his car.
In 2005, the actor was tried and acquitted in the murder of his wife, Bonnie Lee Bakely, but was later found liable in civil court for her death.
