The topic, write based on Professor Ramirez-Berg lecture regarding the 3 acts film structure. The 3 acts are the introduction which usually runs about 30 minutes, then the complication which is the "meat" of the movie and is 30 minutes to an hour in length, then the resolution is about 30 minutes and is the ending of the film. I remember Professor Ramirez-Berg saying that the ending builds up then ends fairly quick.
To start the film...
Introduction- The first 30 minuets or so we, the audience, gets to know the characters and understand what the main concept of the storyline is. We learn that Doug is getting married, and he's going to Vegas with some friends (Phil, Stu, & Alan) a few days before his wedding. We also learn a little background info on the characters that are involved in the rest of the film with Doug.
Complication- This is when the story gets going! We see the guys go to Vegas and have a wild and an unforgettable (or in there case unmemorable) night. The guys have a CRAZY night and when they wake up the following morning, they realize they have lost the groom, Doug. So the boys retrace everything they did the night before and attempt to figure out what all happened. The guys encounter many hilarious antics and the story line gets better (at lease in my opinion). This section of the film fits within the 30-60 minute time frame.
SPOILER ALERT
Resolution- In the final minutes of the film, I'd say the last 20 minutes (give or take some), they gang finally finds Doug! After all there back tracking they finally find Doug, then it's a race to the alter, literally. We see the guys solved there problem which was Doug gone missing and they resolved the situation by finding him and getting him to his wedding. The movie ends with Doug's wedding.
(Not too sure, but I think the unrated version of the film ends with the camera scene, the one where the guys look at the camera one last time to see how wild of a weekend they had)
And the unrated version includes more extended scenes and runs about 10 minutes longer than the theatrical version.
