But as far as Pitt was concerned, the extra-special guest stars were his parents, Bill and Jane Pitt.
The couple strolled the red carpet with Jolie, who looked stunning in a strapless black dress.
And the actress certainly played dutiful host, declining to chat with some reporters saying, “I have to stay with them.”
Pitt, for his part, looked dapper in a bowtie and tux – and still rocking his old-school mustache.
In fact, he said, the entire event was designed to channel old Hollywood glamour.
“It’s a movie in the vein of the classics,” he told Entertainment Tonight. “[It’s a] classic epic, dealing with life and love, and all that fantastic stuff.”
