Voice Over and Montage

For the start of the film I thought about doing a 20-30 second montage of pictures of Lucy and Mathew or just Mathew with a voice over telling the story in a nutshell by Lucy. Instead of trying to film Mathew in Afghanistn being blown up or their lives I thought that it could be just context with Lucy explaining the story.
I think a voice over with pictures can make it seem more realistic and emotional as it is just one voice with images and it makes that persons voice seem more important and dramatic as that is the only thing you hear but it also draws you in/emphasis it more.

Here are some of the images I chose and why:

This image I think shows how they are non-identical twins as they are both at school on their last day sharing their memories together. Their facial expressions make it seem humorous.

This is a picture of him looking smart and smiley which I think would be used for something like a montage to represent somebody as it's formal and classic.
