Decision changes: The ending

I have decided my opening sequence is a bit too much like a trailer. It has a very definitive ending when the main character Heidi gets stabbed in her bedroom.  This is similar to the start of Scream, the (who you assume will be) main character Casey is murdered within the first 10 minute of the film.

This is unexpected as we assume she is the main character and will be featured through out the film. Much like in my film.

This doesn't really signify that its the start of a film. To counteract this I am going to add in an extra shot at the end. This will most likely be an establishing shot of a location where the next piece of action will take place. The dream and murder featured in the opening sequence would be an important event integral to the story and referenced later in the film.
