Romantic Comedy Trailers - 'Knocked Up'

I am now going to look at five existing trailers for films from my genre, and list how the rom-com/farce genre is presented in each of these trailers. 

Knocked Up

• Main production company is Universal - common for rom-coms
• Classic male and female leads
• Upbeat music
• Quick cut to stupid and irresponsible behaviour, from sophisticated behaviour, accompanied by immediate change in music
• Reference to other rom-coms
• Taglines are more like a muted voiceover narrating the base of the story
• High-key lighting 
• Party/club scene
• Meet cute in the club
• Both of the main leads have a best friend (confidant character) 
• The best friends of the leads start flirting
• The male lead being goofy and dancing stupidly
• Clip of them in a sexual setting
• Compliments 
• The 'morning after' clip
• Talk about her being pregnant
• Unintelligent replies which leave space for audience laughter (where the music stops)
• Quick clips showcasing everyone's feelings about the situation
• Solution: get to know each other
• Fades as an editing transition, common for rom-coms
• Summer release - typical for rom-coms
• Jokes/laughter
• Advice given from one of the lead's friends about marriage
• Clip of the male and female leads holding hands for the first time
