While filming the scene in Mockingjay where Katniss leads a group of people through a tunnel filled with smoke, one of the smoke machines started malfunctioning and became so dense, that Jennifer Lawrence and the other actors became lost inside the smoke!
Thankfully, everyone made it out. Here’s what a source on set said:
“It was horrifying… Filming came to an abrupt halt when this fog machine broke and began spewing so much dense smoke during a tunnel sequence that Jennifer literally disappeared from sight – and everybody panicked!”
The incident sounds quite traumatic as apparently the actors could only be located by the sound of their coughing and gagging and it was impossible to see them through the smoke.
The source continued “After several scary minutes, a rescue crew finally found the star and carried her out, hacking and gagging. Jennifer’s one tough gal, but she looked really shook up and kept complaining she felt very nauseous – like she was suffering from vertigo.”
