What scares the stars on Halloween?

Snakes. Guns. Violence. Some scary stuff is universal, and even celebrities aren’t immune.

LOS ANGELES — Snakes. Guns. Violence. Some scary stuff is universal, and even celebrities aren’t immune.

Here’s a look at the secret fears spooking the stars this Halloween:

• “If the snakes come in the room, Vivica is jetting onto the other side of the room, for sure,” says Vivica A. Fox. “Oh, when I was a little girl I almost got bit by one. My family is from West Point, Miss. So they’re taboo.”

• “What scares me is having a gun pointed to my head,” says Gerard Butler. “It’s just you never know. Is this it?”

• “What scares me personally is mob rule,” says Inglourious Basterds star Michael Fassbender. “That’s the one thing that really sort of scares me in life is when people get into a frightened frenzy and they sort of join up and the mob mentality takes over. And that can be like a tidal wave.”

• “I don’t know if this is something to be scared of but one thing I find shocking is really fast, random violence,” says musician-director Rob Zombie. “You know, like when you see things happen, you’re like ‘Oh my God,’ you know. Growing up, when I moved to New York in the ’80s, New York was such a violent town… I remember standing in line on 42nd Street at McDonald’s and all of a sudden, this other guy stabs this other guy right in front of me. Like boom! It’s like this whole bloody mess. And you’re like where did that come from?”
