Research and planning- Initial ideas for film opening

As a group we produced a spider diagram of initial ideas for our film opening. We initially wanted to to do a thriller so we could build suspense and mystery, however we found it difficult producing a good idea which seemed like it was a thriller, as we originally came up with an idea for thriller which did not communicate any elements of thriller. I personally came up with an idea for a romance film, and as a group we developed it and came up with other improvement ideas on the film opening. We decided to have the film title as 'Engaged' and our original idea was to have three female characters getting ready e.g. close up shots on shoes, clothes, make-up etc. after I had this idea I realised it was similar to 'Devil wears Prada" and then have a split screen into three to show the three female characters and meeting up at a bridge, and one of them would announce that they are engaged. We then starting to think of aspects of engaged and romance, so we then developed an idea of a flashback scene of the proposal. We also tried to combine thriller with romance, however we found it quite difficult to produce an idea like that as it is quite hard to do and also it would be quite difficult to show that in a two minute opening.
'Devil wears Prada' scenes which were similar to my idea of the beginning:

One of the group members suggested an idea to do with New Years Eve, so we all came up with idea of a proposal at a new years eve party, however realistically if it were a new years eve party it would consist of many people, so I suggested that it could be a proposal at a new years even dinner with the male and female characters. So we all then developed further ideas about this. 

As a group we then developed that idea into a more detailed idea which was the basic storyline of the opening of the film. However, as a group more ideas about our film opening are being suggested, so as a group we would listen to each others ideas and may try to combine some of them.
