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.

At the end of the commercial, "Anyone but you" star Sydney Sweeney delivers the film's iconic line after Meg Ryan gives another table-rattling performance.

The stars of the 1989 romantic comedy made their return to the legendary Katz's Deli in New York City to star in an epic ad for Hellman's mayonnaise, the brand released today on YouTube. Sitting across from each other at a deli table, the stars replicate the set-up for what is now the iconic "I'll have what she's having" scene.

It's a 'When Harry Met Sally' reunion! Billy Crystal and Meg Ryan joined forces for an upcoming Super Bowl spot for Hellmann's returning to Katz's Deli on New York's Lower East Side for the first time since their 1989 romantic comedy 'When Harry Met Sally' was released.
