Hollywood Heritage has announced a unique “wedding” of two costume pieces at a screening of the film in which they appear on July 13 on the Paramount Studios lot.

Actress Jeanette MacDonald’s wedding dress from director Ernst Lubitsch’s classic “The Love Parade,” owned by private collector Greg Schreiner, will be re-united with the gown’s 20-foot train from the Paramount archives for this special benefit.

The event will begin at 1 p.m. in the studio’s Paramount Theatre, beginning with a discussion with Paramount costume archivist Randall Thropp and Schreiner. The pair will discuss celebrated designer Travis Banton and his contributions to the film, as well as to other classic Hollywood movies of the Golden Age.

Also in attendance will be Nicola Lubitsch, daughter of director Lubitsch. Film historian and author Leonard Maltin will moderate the discussion. The screening of the film will immediately follow.

This special event will raise funds to care for Hollywood Heritage’s historic Lasky DeMille Barn, which houses its museum and is the landmark structure where Hollywood’s first feature-length film, “The Squaw Man,” was made in 1913. Proceeds will help to maintain the historic structure, which was built in 1901.

“Ernst Lubitsch is universally celebrated as one of Hollywood’s true masters of the romantic comedy, and even in this early talkie with Maurice Chevalier and Jeanette MacDonald in her debut, the ‘Lubitsch Touch’ is readily apparent,” Hollywood Heritage Board President Richard Adkins said.

Event tickets are priced at $50 per person and tax deductible to the extent allowed by law, and will offer ticketholders admission to the film screening, free parking on the Paramount lot, a special souvenir program, refreshments and the discussion.

Paramount Studios is located at 5555 Melrose Ave. For information and tickets, visit brownpapertickets.com/event/4265482.
