Zachary Quinto is one convincing actor! The Heroes star found himself being questioned by cops this week whilst he was filming a video for comedy website, Funny or Die.

Zach was pretending to hold up L.A. bakery Kiss My Bundt when a concerned citizen called the police.

Bakery owner Chrysta (how American is that name?) Wilson told Eonline:

“When someone saw Zach hold up a real gun and scream, ‘This is a goddamn hold up!’ they called the police,”

To make it worse, someone called the police again during another take of the same scene but Chrysta is not surprised.

“Zachary is scary as hell,” she says. “I was in the back, making batter, and he was running through the script. All I could hear was, ‘Nobody f–king move!’ He plays evil very well.”

In order to finish the video in peace, Quinto and director Hank Nelken toned things down.

“They knew if the cops were called again, the set was going to be shut down,” Wilson said. “They were whispering their lines in the alley. They knew they had to nail it on the last take.”
