Take a look at your trailer. Is your trailer congruent with your hook and the marketing elements we covered earlier? If not, I suggest you recut and refine your trailer to make sure your marketing message is consistent. In doing this you will have to find the balance between showing enough to sell your movie and giving away so much that you spoil the story. And since your movie trailer will be posted on various websites, you should also add a title card with a link to your movie website.
