Anne stunned in a lustrous, midnight-black Richard Nicoll gown, and she upped the style factor with stunning, custom-designed hand jewellery by James Banks Designs.
The actress, 31, kept her short locks casually tousled, completing the '90s-worthy look with a dark and smoky eye.
Jessica, 37, was every bit the vision, dressed to the nines in a unique, black Givenchy Couture gown, long sleeve with waist-high slits revealing a sexy lace slip.
The Oscar nominee wore her signature crimson locks in a finger-waved, old Hollywood style, swept to one side and revealing striking emerald earrings.
The sci-fi film explores the concept of wormholes, better known as celestial pathways that theoretically connect space and time. Travellers take a voyage through the wormhole in an effort to understand its capabilities, and to search for new inhabitable galaxies.
Variety's review of the film called it "a visionary sci-fi trip that stirs the head and the heart in equal measure."
The premiere, which took place at TCL Chinese Theatre on Sunday (Oct. 26), also hosted Interstellar co-star Matthew McConaughey and his wife, Camila Alves.
Interstellar will be released in theatres on Nov. 5, 2014.
