"The Hunger Games: Mockingjay Part 1" is a much awaited film of "The Hunger Games" trilogy. It will be aired late in the year and fans are excited to watch it. Jennifer Lawrence, who stars in the movie as the heroine, Katniss Everdeen stars alongside Josh Hutcherson and Liam Hemsworth.

According to the crew on the set, the set is made safe for the actors but producers of the movie make sure that they do most of the action in order for it to look as realistic as it should. Things however weren't quite as safe as it should have been while Lawrence and the others were filming on the set of "The Mockingjay Part 1".

According to reports from blastr.com, a source has said that:

"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."

Hollywood's sweetheart, Jennifer Lawrence was supposed to be leading a rebellion through the tunnels when the fog machine had gone haywire and the actors were surrounded by too much smoke, they were stuck in the tunnel and they could only hear them coughing through the smoke. The source had also said that:

'Shut off the smoke machines, get those big fans running ... and get Jennifer out of there!'"

They would certainly want the movie to look as real as it can get and the stars certainly want to do everything they can for it to be a great movie for the fans of the movie but sometimes they just have to take care of themselves.

Everyone was safe as a team was able to get them out of the tunnel in time but according to the source some still felt a little shaken, the source had said:

"Jennifer's one tough gal, but she looked really shook up, and kept complaining she felt very nauseous - like she was suffering from vertigo."

Looks like the movie is something everyone would enjoy watching since the actors have made sure to work hard on each scene of the movie, "The Hunger Games: Mockingjay Part 1".
