Sticking with the theme of romantic comedies, let's talk about "Clueless". Alicia Silverstone and Paul Rudd positively light up the screen with Stacey Dash and the late Brittany Murphy, and the script is vaguely based on Jane Austen's "Emma". The film is also credited with popularizing the phrase "as if" to express disbelief, which we take for granted now. It should also have been credited with creating magic, self-healing cars.
Remember when Cher took her driving test? She wasn't exactly brilliant, was she? In fact, she managed to smash one of the wing mirrors off her car when she hits another vehicle. Not to worry, though, because in the next scene it's right back there like nothing ever happened to it. Maybe she had a spare one in the glove box and she was able to get it stuck back on very quickly. Or maybe this is just poor attention to detail.
