Nicole Kidman and Jamie Lee Curtis have been friends since 2004 and have both mothers of two daughters. Their bond formed during filming Scarpetta, a thriller based on Patricia Cornwell’s novel series. Jamie Lee revealed that the two recognized their mutual responsibility in creating projects like Scarpeta. Nicole Kidman echoed this sentiment, stating that there is no one in Hollywood without Jamie Lee and that they have a "sister energy" in each other. The pair also bonded after the sudden death of a mutual friend, whom they did not name. Their friendship was formed from an email from Amy Schumer after watching her comedy, which led to their instant chemistry.
