Stylishness to infinity and beyond!

George Clooney attended the premiere of his new movie, Tomorrowland, on Saturday, May 9, at Disneyland, and he brought two very special (and well-dressed) ladies as his dates: his lawyer wife, Amal Alamuddin, and her niece Mia.

Ever the dapper leading man, Clooney, 54, sizzled in an all-black ensemble, including a black suit with a slight sheen, an ebony button-up shirt, and patent shoes. He rocked his salt-and-pepper locks parted to one side.

On his arm, Alamuddin, 37, stunned in a coral and black Antonio Berardi minidress, which she paired with dangling earrings and metallic heels, piped in lime. The London-based barrister styled her chocolate mane into loose waves, pinned to one side, and added a watermelon-hued lip—a perfect match to her frock's ruffled skirt.

Last (and certainly most adorable), Alamuddin's niece Mia (the daughter of Amal's sister, Tala) got a taste of the Hollywood life while wearing a white cocktail dress with yellow flowers embroidered throughout. She added a tiny black belt at her waist and ballet flats.

After the trio posed for photos at the beginning of the carpet, the ladies went inside the AMC Theatre while Clooney answered questions about his futuristic new film, inspired by the mini-theme park within a theme park at Disneyland.

"I [visited Tomorrowland] when I was a kid, like 6 or 7 years old," Clooney—whose costar Britt Robertson also attended the event—told Us Weekly. "Tomorrowland then was what we thought the future was going to look like now. It looked like the Jetsons!"

Musing on the technology that actually made it to 2015, Clooney added, "I thought we'd be driving around in floating cars by now. What happened? I want a jet pack just to get past the 405 freeway!"

After the screening, Clooney, the Alamuddin ladies, and more friends hopped the monorail to the actual Tomorrowland, where a private afterparty was held. There, guests posed for pictures with a space-outfitted Mickey while the adults sipped on "Tomorrowland Orbiters" made using Clooney's Casamigos Reposado Tequila.
