When Maya and Ron are dancing at the Christmas party, they end up dancing the tango while having a disgruntled conversation. This nearly mimics the exact same scene from The Wedding Planner, in which Mary and Eddie also dance the tango.
The photo that Maya finds on her Facebook page of her with President Barack Obama and First Lady Michelle Obama is a real photo from the inaugural ball in Washington DC in January 2009 which Jennifer Lopez attended.
Second Act was shot entirely in New York. The filming started on October 20, 2017, and ended on December 15, 2017. Peter Segal wanted to make Manhattan a full-fledged character. Other places the team has invested in include the Bethesda Fountain in Central Park, the High Line, the streets of Soho, the South Street Seaport area, Madison Square Park, the Food Bazaar in Queens, the Rockerfeller Center, Villard Mansion at Lotte New York Palace Hotel, Dean & Deluca's, inside a metro train of the Metropolitan Transportation Authority, and the wharf of an air train.
Principal photography began on October 23, 2017, at Food Bazaar Supermarket in Queens, New York and has continued in The Bronx and Manhattan, including Michael Jordan's Steakhouse in Grand Central Terminal. Filming wrapped on December 15, 2017.
