If Zachary Quinto isn't careful he'll wind up on America's Most Wanted one day.
The Star Trek star found himself answering to cops recently while filming an upcoming Funny or Die video at L.A. bakery Kiss My Bundt.
In the comedy bit, he plays a pistol-wielding robber.
"When someone saw Zach hold up a real gun and scream, 'This is a goddamn hold up!' they called the police," Bundt owner Chrysta Wilson tells us.
And get this, the cops were called a second time during another take of the same scene.
Wilson said she's not surprised the make-believe drama appeared to be real...
"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."
Quinto and director Hank Nelken realized they better tone things down if they wanted to get their work done.
"They knew if the cops were called again, the set was going to be shut down," Wilson says. "They were whispering their lines in the alley. They knew they had to nail it on the last take."
