Idea for Opening

We were asked to come up with an opening idea in the lesson to see if we could. We each had to come up with an idea and then in our groups we talked about it and refined our idea. This is the idea that i came up with and some aspects of it have been used in our final idea.
Intro
In the park a man is out playing with his son. He throws a ball to his son but it goes into the bushes. His son then goes to try and find it. Meanwhile in the bushes a man is peeking on the dad. POV shots of the dad. Suddenly the boy comes back and discovers his dad lying dead on the ground. The film would then go on to show the son much older as a cop trying to solve a similar case which turns out is done by the same man that killed his dad all those years ago.
