HBO Max has unveiled a promotional trailer showcasing returning series and highly anticipated titles, including a first look at season four of "The Gilded Age." The period drama, created by Julian Fellowes, earned its renewal in July 2025 after three successful seasons exploring the wealth and social dynamics of New York's elite during the 1880s and 1890s. The network also teased new "Harry Potter" footage, extending the franchise's presence on the streaming platform beyond the original eight films.

The trailer represents HBO Max's strategy to consolidate viewer interest around its prestige programming and franchise tentpoles. "The Gilded Age" has become a cornerstone of the network's drama slate, building on the success of Fellowes' previous hit "Downton Abbey." The show's renewal signals confidence in its ability to attract the older, affluent demographic that favors period dramas and sophisticated storytelling.

The inclusion of "Harry Potter" material underscores Warner Bros. Discovery's commitment to maximizing the wizarding universe's value across multiple platforms and formats. This follows the recent casting of Aaron Taylor-Johnson as a younger version of Dumbledore, suggesting the studio continues developing adjacent projects within the franchise.

HBO Max's mixed approach in this trailer reflects the streaming industry's current reality. Prestige dramas like "The Gilded Age" anchor subscriber loyalty through awards recognition and critical acclaim, while franchise properties like "Harry Potter" provide cultural currency and broad appeal. The strategy acknowledges that streaming platforms must balance programming that attracts cinephiles and literary enthusiasts with tentpole entertainment that captures mainstream audiences.

Francesca Orsi, executive vice president of HBO, commented on the slate, reinforcing the network's focus on quality storytelling. The trailer appears designed to manage subscriber expectations during a period when new content rollouts have become unpredictable across the industry, with HBO Max and competitors balancing production schedules and strategic releases.
