Rose Byrne Turns Heads in Plum Gown at ‘Art’ Broadway Opening Night

The "Instant Family" star dazzled on the red carpet at the opening night of the star-studded play this week. Her appearance comes after her new comedy-drama premiered at the Toronto Film Festival.

Rose Byrne attended Broadway's "Art" opening night on Tuesday evening, September 16. The distinguished affair, which saw Hollywood A-listers including Anna Wintour and Goldie Hawn in attendance, took place at the Music Box Theatre in New York City.

Byrne looked stunning in a deep plum, floor-length satin gown. The dress, which accentuated her figure, featured thin spaghetti straps and a structured bodice with rose-like cutout details at the bust.

The "Peter Rabbit" star kept her accessories minimal, wearing only a delicate bracelet, and opted for natural makeup with a rosy lip. She completed her look with dark-colored strappy heels.

"Art" stars "The Watcher" alum Bobby Cannavale, comedian James Corden, and "How I Met Your Mother" star Neil Patrick Harris. The play follows three friends debating over the value of a ridiculously expensive painting.

As the description reads, "What begins as a polite debate over aesthetics and taste devolves into a clash of egos and resentments. Can their friendship survive, or will one of them finally draw the line?" The show will run until its final showcase on December 21.

Byrne's appearance at the opening night comes just days after her own comedy-drama, "If I Had Legs, I'd Kick You," premiered at the 2025 Toronto Film Festival on Friday, September 12. The film, in which she co-stars opposite Conan O'Brien, first debuted at Sundance in January.

It follows Byrne's character, Linda, as she attempts to navigate turbulent life, from her child's mysterious illness and her absent husband, to a missing person case and an increasingly hostile relationship with her therapist. The film is slated for release on October 10.
