Cara Delevingne and Kendall Jenner React to New 'Valerian and the City of a Thousand Planets' Trailer

"I haven't even seen the film yet. I'm dying!" Cara Delevingne exclaimed at a special 3-D preview of the Valerian and the City of a Thousand Planets trailer in Hollywood on Monday. "Every time I see a little bit, I'm just, like, salivating."
And here's that latest little bit for you: the newest trailer is now online, featuring Avatar-like blue aliens tasking Agents Valerian (Dane DeHaan) and Laureline (Delevingne) to be the guardians of their galaxy. Keep your eyes peeled for Rihanna's cameo, dressed a latex nurse's costume to at an intergalactic cabaret.
Delevingne's pals Kendall Jenner and Jaden Smith snuck into the back row of the theater for the preview event and, as the trailer concluded and the theater light came on, Smith hollered, "Run it back!" (which it promptly was) while Jenner gushed, "That was so sick." "Amazing!" Jenner later told ET at an after party. "We're so proud of her and we can't wait to see it."

ET also sat down with Delevingne and French director Luc Besson (La Femme Nikita and The Fifth Element) to get their reactions to the trailer, talk working with Rihanna and find out how many Valerian sequels they could make.
ET: You know you've made it when you're having a premiere for the trailer of your movie. That was pretty frickin' awesome.
Cara Delevingne: I agree.
Luc Besson: Yeah, but there are so many big, big competitors this summer [that] we have to scream that we exist! We're here! You know, between the Spider-Man and Planet of the Apes and all the big films, we're brand new. It's a first. It's not a sequel. It's not number 17.
Cara, had you gotten to see any of the movie in 3-D yet?
Delevingne: I had, actually -- once before -- but not on that big a screen. That was the first time seeing it in a proper, proper, proper cinema. It's so crazy. Every minute is just like, a pinch-me moment, and I can't believe this is real. It's so odd. I find it so strange. I just-- I'm so happy.
How does this compare to what was envisioned on set, because I assume it was mostly green screen during filming to a certain extent?
Delevingne: Blue screen! But the world that Luc pictured, that he described was exactly this. The amount of love and knowledge that he has of this comic, he literally has translated it into this movie. I honestly think the movie is going to blow my mind, because every time I see it, the visual effects just completely blow my mind. Obviously, when you're acting on set and you're talking to a tennis ball, it's like, "What the f**k? What's going to happen? How's this going to turn into a 20-foot monster?"

We also get a kickass Rihanna moment. How is working with her as an actress?
Besson: The first thing when I met her, I wanted to be sure that she wants to be an actress. Because her entourage says she wants to, but I need to hear it from her. She's so talented in everything else, [but] you can't take someone just because they want to try or they want to have fun. With this kind of film, you need someone who really wants to be serious about acting. And she was definitely serious about it and very, very low profile about it. Very like, "I'm a beginner as an actress. Take the clay and play with it." The hard part is to get her on set. [Laughs]
Delevingne: On set she was incredible. I always said to her what an incredible actress she could be, because she's an amazing performer, you know, but to actually see her be able to do it on screen I think will be really incredible. I think people will really enjoy it and I think they will be really surprised.
Besson: And they [Delevingne and Rihanna] have something in common. They don't fear. When they trust, I guess, the director, they really let you in. They let you manipulate them. They're not scared of being ridiculous. They don't care. They just give, and for me, it's just what you want. She's scared of nothing.
Cara, did you have any familiarity with the comic book [Valérian and Laureline] or was this all new to you?
Delevingne: No, I'd never heard of it before in my life. But it's funny, because after Luc told me of it, the amount of people that have come up to me, like, "Oh my god! I know about Valerian." A lot of people I know have known of it and I don't know why I haven't, because I've been a fan of Star Wars and many other things and they have all taken so many parts of their stories from Valerian, so it's, like, so interesting to see where that comes from.
You have your posse here supporting you tonight, have you since tried getting all of your friends into Valerian, too?
Delevingne: Yeah, 100 percent. I'm like, "C'mon guys! Get into it!" I think comic books are amazing.

As a director, what balance do you strike between making a standalone film versus setting up a potential franchise?
Besson: I don't think this way. I love the two characters and I can make number two, three, four, five, six, seven-- until she's tired of it. But I love them. I can spend 10 years with them. The good thing is they are two space agents and every film is you say? Enquête...
Delevingne: Like, what?
Besson: You know when you try to find who is the killer...
Delevingne: A mystery? A crime? Uh...
Besson: They are on an investigation. Every film is an investigation. They're cops, basically. Space cops. And they have a problem -- a big one, in this one -- and they have to solve it.
Cara, how do you feel when you hear he's ready to have you in Valerian 2, 3, 4, 5, 6?
Delevingne: I mean, c'mon! What do you think? That's a dream. I had the best time of my life.
Besson: [Imitating an old woman's voice] "Valeriiiiian, c-c-come over here."
Delevingne: I'll be in my rocking chair! Like, I would be honored to be able to be doing this film forever and ever and ever, honestly.
Valerian and the City of a Thousand Planets hits theaters on July 21.
