Meg Ryan and Billy Crystal recreated a classic scene from "When Harry Met Sally" for a new Super Bowl ad, with a special appearance by Sydney Sweeney.

It’s a reunion 35 years in the making, thanks to mayonnaise. More than three decades after the romantic comedy “When Harry Met Sally” first hit theaters, Billy Crystal and Meg Ryan are finally back together.

The two actors revisit an iconic scene from their legendary romantic comedy in the commercial, a nostalgia play titled “When Sally Met Hellmann’s” (watch below). Ryan and Crystal play friends whose connection turns romantic in the 1989 movie written by Nora Ephron and directed by Rob Reiner.
