7. Think it sounds glamorous to work as an actor or an extra in a major movie? Check this: the prom scene was filmed at Seattle's Century Ballroom in the summer of 1998. During the 3-day shoot, the temperature skyrocketed to over 90 degrees! More than three hundred extras were called in, wearing full prom regalia and corsages and absolutely melting in the heat. 8. Heath Ledger is originally from Perth, Australia. Since he went to high school outside of the U.S., he wasn't sure what to expect when he arrived on location. "In Australia, we always see American high school movies, and they always have yellow school buses. I just didn't think they really had [them] until I came over here and saw them for myself!" There was initial concern on the part of the producers about Heath's accent, but as director Gil Junger put it, it works because "it makes him more interesting, mysterious, and sexy." 9. Fellow CS-celeb Andrew Keegan plays Joey Donner, a high school stud who desperately wants to go out with Bianca. Commenting on Andrew's work, the director noted, "I cast Andrew because I felt, in many ways, he was this guy. He's cool and very confident about the way he looks. I'm sure he's very confident with women, which is how this character needs to be. The delicate balance that I've been trying to get with Andrew (and have gotten because he's a good actor), is how do you be cocky and overly sure of yourself, and not seem smarmy? I've tried to keep him grounded so that the audience will know that inside, he really is a good guy." 10. Can you imagine Larisa playing a shrew? According to producer Andrew Lazar, initially "Julia Stiles and Larisa Oleynik both liked the character of Kat. When Julia walked in, it was so clear that she was dead-on Kat. However, Larisa is so extraordinarily talented that we wanted to see her as Bianca." Director Gil Junger agreed, saying, "Larisa lights up the screen. She has a difficult part, because she has to play a girl that the audience doesn't particularly like in the beginning because she's materialistic and self-centered... She's a real person, and she too is just hiding. That's a fine line for an actor to walk, and Larisa does it beautifully."
