Jennifer Lawrence Reveals Two On-Set Pill Mix-Ups That Made Filming a Nightmare

Jennifer Lawrence is opening up about a pair of stressful — and oddly funny in hindsight — mistakes involving sleeping pills that happened while she was filming major movies.

The actress shared the stories while reuniting with her Don’t Look Up co-star Leonardo DiCaprio for Variety and CNN’s “Actors on Actors.”

Lawrence explained that she’s extremely serious about sleep when she’s working. That’s why one mix-up during the filming of Red Sparrow hit her especially hard.

Instead of taking a sleeping pill, she accidentally took Adderall.

“I didn’t sleep all night,” Lawrence said. The result was pure panic on set the next day. She recalled taking hot showers to calm herself down, all while preparing to deliver complicated dialogue — including the phrase “Senate Armed Services Committee” — in a Russian accent.

“That sucked,” she admitted.

But that wasn’t the only time pills caused chaos.

Lawrence revealed that years earlier, while filming The Hunger Games: Catching Fire, she accidentally took Ambien in the morning, thinking it was something else.

DiCaprio reacted in disbelief, calling the mistakes “key screwups.”

Lawrence said the Ambien left her hallucinating during a dance scene with Philip Seymour Hoffman. The drug also wrecked her focus, making it nearly impossible to remember her lines.

Her confusion reportedly irritated co-star Elizabeth Banks, who eventually lost patience as Lawrence kept stopping the scene to ask what her lines meant.

“She just threw her sides and said, ‘Fine, let’s just keep talking about it,’” Lawrence recalled.

Catching Fire marked Hoffman’s first appearance in the franchise as Plutarch Heavensbee. He later filmed Mockingjay Part 1 and Part 2 before his death in 2014 at age 46.

Lawrence famously played Katniss Everdeen across all five Hunger Games films, and she may not be done with Panem just yet. She is reportedly close to returning to the franchise in The Hunger Games: Sunrise on the Reaping, which would reunite her with Josh Hutcherson, Woody Harrelson, and longtime director Francis Lawrence.

For now, fans can rest easy knowing Lawrence survived those sleepless, surreal days — and learned exactly how important it is to double-check the pill bottle.
