The best way to start this assignment is to brainstorm what kind of movie you would want to give an intro for. What is your favorite genre? What movies have you seen that you enjoyed the most? These questions will help determine what type of movie you want to do and what the plot should be like. Now that you have a general idea, search on Google, YouTube or any other media website for a video that fits your story. Use a video editing software to create a good movie intro clip. Now write down what you want to say, again think back to what you brainstormed before. After that is done, record yourself reading what you wrote and add that audio to the the clip you created before. Now you have an intro to a movie you would love to see!
