J.J. Abrams has been at the helm of some major franchises in his time, but the Monday premiere of Star Wars: The Force Awakens in Hollywood was an event like no other.

“This is like nothing else in the universe that I've experienced,” Abrams told ET on the red carpet. “Today is extraordinary.”

The director was joined by Force Awakens star Lupita Nyong’o, and the two answered some ET fan questions, including one about their earliest Star Wars memory.

“My earliest Star Wars memory was being off of school in Kenya and curling up on a poof in my living room watching the movie,” the 32-year-old actress said, adding that attending Monday’s premiere was “otherworldly.”

Nyong’o’s outfit was also out of the this world. The actress donned Alexander Vauthier couture and a Princess Leia-inspired updo for the premiere.

Abrams, 49, also opened up about taking on the celebrated franchise, admitting that all the beloved characters were “really fun to write.”

“I would say that probably Han was the most fun, only because he has moments that sort of allow you to play in that kind of celebratory ironic way,” he added.

The director posed on the red carpet with Star Wars creator George Lucas, and said that Lucas’ stamp of approval on the new installment was very important to him.

“It means an enormous amount,” Abrams said. “I don't think there is a day that goes by that we weren't aware of and grateful for. We do the best we can to make him proud!”
