London, Feb 20 : Actress Scarlett Johansson has revealed how she continued acting a scene even when actor Liev Schreiber's saliva was dripping from her face.

Schreiber, 42, and Johansson, 25, were performing in Arthur Miller's Broadway show 'A View From The Bridge' when the incident took place.

In the play Johansson portrays a 17-year-old girl in 1950s New York with Schreiber as her uncle, and they had to perform a scene in which they had a heated argument.

But the scene became all too real when Schreiber's saliva hit Johansson on the forehead.

"We're really close to one another and we have these scenes where he's getting really upset and there's a lot of rage," the Daily Express quoted her as saying.

"A couple of weeks ago we were doing this scene. He's right here (in my face) and he's screaming at me and all of a sudden - it happened almost in slow motion - I saw it.

"These pearls of spittle. And then this one asteroid of a loogie (landed on my forehead) made that flicking sound," she revealed.

But Johansson refused to stop the show after the sticky mishap, and continued to perform with saliva dripping down her face.

"Any normal person would wipe it away but I felt this show must go on... he saw it, I saw it. It was awful," she added.

Johansson and Schreiber's limited run is scheduled to end on April 4.
