Ran into filmmaker Ryan Graham at Zodiac earlier this afternoon, just before he was about to give a seminar on special effects.

Graham brought some ingredients to make fake blood splatters with him, which he planned to give to the audience after the seminar.

"I'm hoping people are going to start putting them in odd places," he said.

I reminded him that fake blood splatters aren't that uncommon in Baltimore, and might not freak people out that much.

"Who knows?" he said. "Fake blood splatters are great."
