Ariana Grande Faces Robert De Niro's Infamous Lie Detector in New Fockers Movie Ariana Grande makes her acting debut in the Fockers franchise as Olivia, the girlfriend of Greg Focker's son, Henry. In the trailer for Focker-in-Law, she undergoes a lie detector test administered by Robert De Niro's iconic character, Jack Byrnes. Grande's character reveals a surprising background as an FBI hostage negotiator, setting the stage for comedic confrontations and family drama. The highly anticipated fourth installment in the beloved Fockers franchise, Focker-in-Law, is set to hit theaters this November, bringing back fan-favorite characters and introducing new dynamics. The trailer for the upcoming comedy offers a glimpse into the chaos and hilarity that ensues when Olivia, portrayed by global superstar Ariana Grande, enters the Focker family. Grande's character, the girlfriend of Greg Focker's son Henry (Skylar Gisondo), finds herself subjected to the notoriously stringent vetting process of Jack Byrnes, masterfully reprised by Robert De Niro. The trailer opens with a tense, yet comically executed, lie detector test administered by Jack to Olivia. He candidly explains his protocol, stating, I test all the potential new family members with this machine. This instantly harks back to the original film, Meet the Parents, where Jack's suspicions and elaborate tests were central to the comedic tension. Grande's character, however, appears to be more than capable of handling Jack's scrutiny. She reveals her background as an FBI hostage negotiator, declaring her intention to liberate her boyfriend, Henry, from a seemingly codependent relationship with his father, Greg, once again played by Ben Stiller. This unexpected skill set promises to add a unique twist to the Focker family dynamics, potentially turning the tables on Jack's usual interrogations. While Olivia seems to charm everyone, including the family dog, Greg remains apprehensive about her influence on Henry. He expresses his concern, I’m a little worried about Henry. He’s so innocent and she’s trained to manipulate people. The trailer hints at a potential rivalry between Olivia and Greg, culminating in a bike race where Greg resorts to underhanded tactics to secure a win, further highlighting his protective instincts and anxieties about his son growing up and potentially being influenced by a new, formidable presence. The film's ensemble cast is further bolstered by the return of other franchise regulars like Blythe Danner and Teri Polo, and welcoming “Booksmart” alumni Beanie Feldstein and Eduardo Franco, as well as Owen Wilson. This rich tapestry of talent suggests a comedic outing that will satisfy long-time fans while drawing in new audiences. Robert De Niro himself praised Grande's performance, calling her probably the single funniest scene partner I’ve ever been lucky enough to share the screen with, hinting at the electric chemistry audiences can expect. Ben Stiller, with a touch of playful bravado, quipped during CinemaCon, I guess you could say I’m the new De Niro of the franchise, underscoring the enduring legacy and evolving nature of the series
