here. Sorry about that, george. You know, we're talking about "clueless." One of our favorite movies. And this is part of our incredible flashback. We're having all-star reunion blowouts. THIS IS A STAPLE OF THE '90s. One of the movies we can't stop talking about. You see them on the cover of "entertainment weekly." Rachel smith had the great opportunity to talk to the cast. How much f was that, rachel? Oh, my gosh, sam. The ultimate experience for me. I am just a mad "clueless" fan, as are you. Right? ♪ Rolling with the homeys ♪ oh, yeah. I was rolling with the homeys in "clueless." It was one of the most iconic MOVIES OF THE '90s. And it included catchphrases that many of us are still using today. And getting together with the cast, it felt like the ultimate reunion. I don't know why tai's going without with a high school boy. Get off of me. Reporter: It was the movie that defined a generation. Want to practice parking? What's the point? Everywhere you go has valet. Reporter: With an aun I poll jettic passion for fashion. What is that? A dress. Says who? Reporter: Unforgettable lingo. And take no prisoners attitude. It was a stop sign. I totally paused. Reporter:17 years ago, "clueless" made a certifiable splash across the silver screen, leaving a permanent mark. I'm totally buggin'. Reporter: We decided to catch up with cher, dionne, murray, travis, amber, and christian. While this guy, while they were reuniting for an "entertainment weekly" photo shoot. It's been 17 years. People will come up to me about that movie. It started all of our careers. Reporter: In 1995, the cult phenomenon was a hard script to sell. It almost didn't make it to the big screen. At the time, people were saying, who wants to watch a bunch of young people? Reporter: To say that fashion was its own character in the movie would be an understatement. So, we decided to take a look at some of the most classic "clueless" ensembles. Stacey. Oh, boy. That hat. I thought it was very fashionable. I felt like audrey hepburn. This is quite the famous gesture, missy. People still do that to me. That was not because of the movie. I was just greasy and filthy when we made the film. That was it. Best entrance ever, dude. A striking, young fella. Reporter: Classic. Iconic. The plaid. It still looks good. Reporter: Were you liking the outfits that you were sporting? I liked it. But I didn't understand fashion at all. 60 changes. I was so tired. And I didn't understand why i had to keep having fittings. I kind of hated them. When I saw the movie, i understand. Reporter: But it wasn't just the clothes that made movie history. Give me some of your favorite lines from your characters. Oh. Yeah. You know what I'm saying? My plastic surgeon doesn't want me doing any activities with balls flying at my nose. Mine is -- there goes your social life. Reporter: One cast member was missing, brittany murphy, who passed away in 2009. Is there a memory that you think to when you think of your time on "clueless." The laugh. Contagious. So, so, genuinely sweet. Yeah. For a week, I couldn't believe it was real. Reporter: Your character, cher, had to take her under her wing. And help her come into herself. And taught her sporadically. Sporadic means once in a while. Try using it in a sentence today. See you. I hope not sporadically. Reporter: Where would your characters be today? I think dionne would be a fashion editor in new york. I think amber would be married to an extremely wealthy man. And driveling him crazy. I think I'd be an aging backup dancer for lady gaga. Reporter: Where would travis be? I like travis and tai would probably still be together. And would create some instagram by accident. I would write romantic novels. They're really good. Reporter: And where would cher be? Yeah. Married to her brother. Yeah. Unbelievable. But it really was a fun experience for all of us. It was like being with old friends. They really, truly seem like they enjoyed being back together, reunited again. I also got the scoop on some other a-listers who were considered for roles in "clueless." Check this out. How about reese witherspoon as cher? I could see it. Alicia silverstone beat her out. And carren powers. For murray. And others include zoe dechanel, seth green and lauryn hill. But I think the directors got it right. Could not imagine it another way. Coming up next week, we have
