Some ideas about final project

I'm going to make a ten minutes film as my final project. It will be a digital remix that is made up of video clips from various movies. What I need to do is to decide what the theme is and how to represent it through the video and music.

Here are some ideas about the theme:

• "Life is beautiful/You will see the rainbow."
  
  There are a lot of people who killed themselves in movies because they thought life was too hard for them. On the contrary, there are also many movies telling how beautiful the life can be.
  
  Here I want to put the sad scenes in the beginning, and then inspiring scenes come out later. It aims to express the theme through the comparison. Light music is preferred as the background music.
  
  
• "We are the same."
  
  (We have a lot of things in common though we look so different.)
  
  I would like to use movie clips reflecting people of different races doing the same things, such as fighting for freedom, saving people from dangers, caressing children and scene of family reunion. Light music is preferred as the background music.
  
  
• "A Perfect Day."
  
  It will be a day made up of various lucky things from different movies, such as getting promoted in the morning, meeting Miss. Right at lunch time, and finding the notice of winning a Pulitzer Prize at night. Comic or light music is preferred as the background music.
  
  
• "A Perfect Life."
  
  If the lucky things I found were too many to be put in a single day, I will make them happen in "a perfect life."
  

And I will add more information as I think about it.
