Stars Wars franchise newbie Felicity Jones may play butt-kicking Jyn Erso in the upcoming Rogue One, but the Oscar-nominated actress showed off her softer side on the red carpet for the world premiere as she arrived in a Christian Dior corseted floral gown. Jones glowed in the sheer, metallic number, completing the look with a pair of statement earrings and her hair pulled back in a bun with parted bangs.

As Jones dazzled, fans lined up along the massive red carpet, which shut down a large portion of busy Hollywood Boulevard, to catch a glimpse of the actress and her costars like Diego Luna, Mads Mikkelson, and The Night Of star Riz Ahmed. (And it wasn't just regular fans, there were plenty of fellow celebs, like Jaime King in a breathtaking gold and black strapless gown, who joined in on the intergalactic fun.) The red carpet was such a visual spectacle that there was a huge X-wing starfighter sitting at the top of the red carpet, and plenty of stills from the film and promotional posters lining it, giving attendees more than a few places to snap Instagrammable photos.

As Luna headed inside with a wave in a navy suit, Ahmed, who plays Bodhi Rook in the action flick, told InStyle it felt “surreal” to be at the premiere and a part of a franchise he’s loved since he was a kid. “It doesn’t feel like reality,” Ahmed, who rocked a striped gray suit, told us. “It feels like it’s a childhood fantasy, and in many ways it is. So I’m just trying to embrace it, enjoy it and savor the moment. It’s a privilege.”

As for what die-hard Star Wars fans can expect from the film, producer Allison Shearmur told us they should get ready for a “stand-alone film” with a “completely independent storyline.” She added, “Though we absolutely drive into Episode 4, what happens before that is completely original, and people, we love the Skywalkers. [But,] this movie has all new characters that you will be very happy to meet.”

Speaking of those new characters, Shearmur sang Jones’ praises, saying, “Felicity Jones brings a quiet, strong, intelligence [to the film]. You never doubt that she can take on a big Imperial droid or walk into a room of resistors and convince them, without ever having to raise her voice.”

Rogue One: A Star Wars Story hits theaters Dec. 16.
