“I was like ‘Oh my gosh! F—k, I cursed,’” laughed Diane Kruger at the New York City premiere of her film “Disorder” at Landmark Sunshine Cinema on Tuesday night. The German actress was referring to her appearance on “The Late Show with Stephen Colbert” a few days before where she dropped the F-bomb while imitating a German accent. “I was delirious,” she joked.

Kruger alongside writer-director Alice Winocour was celebrating the American open of “Disorder (Maryland),” which bowed at Cannes Film Festival in 2015. The psychological thriller follows a former soldier (Matthias Schoenaerts) suffering from post-traumatic stress disorder who is hired to protect a wealthy businessman’s trophy wife (Kruger) and son.

Winocour said she was inspired by the stories of soldiers, but was personally drawn to PTSD because of her own struggle with the disease. “I also have experienced PTSD myself — giving birth to my daughter and almost dying of it,” she confided. “I didn’t know if I was dead or alive, but I could hear all the sounds of the electronic machines around me and I think that’s what inspired me.”

Kruger told Variety she was attracted to the film because of the growing sense of emotional disorder. “It’s a psychological thriller with a very slow burn. It takes time to install this sense of neurotic[ism] and paranoia,” explained Kruger. “I love that my character goes from being this trophy wife to this vulnerable person who finds her own life.”

After the screening, Kruger and Winocour snapped photos by the rooftop pool at Jimmy at The James Hotel. Guests including Paul Haggis, Georgina Chapman, Laura Michelle Kelly, and Brandon Victor Dixon (the newest “Hamilton” cast member) enjoyed sliders, chicken and cheese dumplings, and the aptly film-inspired QUI Tequila cocktails “Night Watch” and “Riviera Intrigue” while overlooking Manhattan.

“Disorder” opens in theaters August 12.
