Looking at Professional opening sequences

We have been watching and analysing professional opening sequences. We looked at opening scenes from Fight Club, Scream, Knocked Up and Ferris Bueller's Day Off.

In Scream's (horror) opening scene we are introduced to a young blonde woman getting a phone call. The audience can immediately tell that the caller is not trustworthy , but she doesn't know that yet as she continues to chat to him. At this point we don't even know her name, but the man then asks for her name and she refuses to tell him. She then asks him why he want's to know her name, and he tells her he wants to know her name to see who he's looking at. This is when she finally comes to her senses and ends the conversation. What i liked about this opening sequence it that it went straight to the point, they didn't take too long to set the scene and it didn't feel like it dragged for too long. In knocked up's (comedy) opening sequence, we see a bunch of immature 20-something year olds messing about and smoking weed. We then see a woman who looks like she works and seems organised. She walks out of her small house and into another bigger house. It turns out she lives in her sister's pool house. We see the rest of the family and it shows a woman, her husband and their two kids. The husband and wife are arguing about who is going to pick up the kids from school and the audience can tell that they have some problems. In Fight Club, we first see a flashback sequence where the main character (and narrator) recalls what happened. We see shots of him being pointed at with a gun, and then we see him suffering from insomnia. Then we see him in his office. We are introduced to the character, who is not named,
as soons as the credits end. The credits were at the start of the film and it goes on for quite a while. In Ferris Bueller's Day Off, It opens with a teacher doing the register and calling out Ferris Bueller's name, but he's not there. We then see him in his bed, pretending to be sick so that his parents let him have a day off school. His sister then complains about them favouring him. In this opening sequence, we are introduced to him, his parents and his sister. I like this because they introduced 4 characters in 2 minutes to quickly introduce them.
