Actor Liam Neeson may be known as a action star, but there is one thing that terrifies him i.e. Heights.

The 62-year-old actor admits he suffers from acrophobia and can't even manage to stand on a chair to fix a bulb in a lamp because of the extreme fear, reports people.com.

"We're all just human, aren't we? Somebody might freak out over a snake or a spider. I don't - I pick spiders up and put them outside. But put me on a chair to fix a lamp or something and then, boom," Neeson said.

Meanwhile, the star admitted he's not ready to retire just yet and is trying to make the most of the exciting roles.
