"Fire is catching! And if we burn, you burn with us." These lines could set the tone for "The Hunger Games: Mockingjay."

Jennifer Lawrence was spotted this week in Paris, France filming the Suzanne Collins book-turned-film adaptation of "Mockingjay."

Lawrence, along with other "The Hunger Games" cast members, were spotted filming perhaps the second part of Mockingjay. The final book-turned-movie has been split into two films, a la "Harry Potter and the Deathly Hallows" Parts 1 and 2.

It is unclear which sequences they were filming because they are doing both "Mockingjay" Parts 1 and 2 at the same time.

Perhaps it was Katniss and company in District 13's secret hideout, which was what the rebels call home, MTV News reported. But the sequence could also be part of the story where Katniss is fighting her way through the streets of the "Capitol."

Why Paris? "Mockingjay" was filmed in Ivry-sur-Seine. This is perhaps a pivotal scene of President's Snow "Capitol" or of the District 13 rebels, one French source reported.

The third film will see Lawrence's Katniss challenge the commander of Panem, President Snow, played by Donald Sutherland, the Express reported.

Lawrence wore a futuristic blue jacket with a hood; her fellow cast-mates including Liam Hemsworth, and Evan Ross joined her for lunch in the French capital.

The cast will also feature the late Philip Seymour Hoffman. Hoffman died of an acute drug mixture in February of this year. Hoffman's scenes in the "Mockingjay" were already filmed, while other scenes will have him digitally added.

"The Hunger Games: Mockingjay Part 1," is expected to be in theaters on Nov. 21 2014.
