First impressions are huge. Not just in job interviews or on first dates, but also on the big screen. The first time we, as an audience, meet a movie character, we're going to form strong feelings about them right then and there.
For example, if a director wants the audience to get behind the action hero, maybe don't show him kicking a dog in the first scene and then punching his grandmother in the second. It'll just make it that much harder to root for the guy in the climactic gun battle.
Likewise, if the director wants his female lead to ooze sexuality, it might not be wise to first show her vomiting in a bathtub while wearing a dirty, tattered smock. Sure, some folks might be into that kind of thing, but most of the audience is going to have a tough time getting onboard.
Think of the sexiest movie character you've ever seen. (Don't think about them too hard, though, you'll need at least one of your hands free to click through the list.) Chances are, whichever character just popped into your head made a strong, sexy as hell first impression. That wasn't by accident.
So please, enjoy reliving your first encounters with these enticing characters. And if you haven't seen them before? Well...you're welcome.
