Anne Hathaway and Jessica Chastain couldn't have been more stunning! The gorgeous pair stepped out for the premiere of their film Interstellar (which co-stars Matthew McConaughey) at the TCL Chinese Theatre in Hollywood, Calif., last night looking every bit like glamorous Hollywood royalty.

Hathaway showed off her tousled bob and décolletage in a sexy Richard Nicoll slip dress that she complemented with a dangling backwards necklace (similar to the one she wore at the 2013 Oscars) along with a James Banks Design hand-chain bracelet created by someone very special to the actressher husband Adam Shulman. "My husband designed my bracelet," Hathway tells InStyle of the intricate accessory. "I love it."

Also opting for a dark hue at the event, Chastain dazzled in a black Givenchy Couture gown that featured a plunging back and sheer lace side panels that she paired with bold emerald green Fred Leighton earrings. "I love that my friend Riccardo Tisci designed my dress for Givenchy. I like the little peekaboo, and I think that it’s perfect for the Chinese Theater," Chastain says. "This is the biggest premiere I have ever been to for one of my films, and this suits the occasion."

Hathaway and Chastain were delighted to be in each other's presence on the red carpet, but the duo was even more excited about the release of the movie, which tells the emotional story of a team of explorers who undertake a mission beyond this galaxy to save Earth and humankind. "The movie is thrillingyou sometimes can't breathe its so exciting," Chastain says. "You can expect incredible visuals, science, and action, but at the core it's a story about the powerful bonds of love and family. You might even shed a couple of tears!" Hathaway added to that sentiment: "This is an unbelievable, exceptional film and it deserves to bee seen in movie theaters."
