You would only be able to prevent the use of the footage if:1) you can show that you were induced to sign the form by fraud (a material, or important, lie about what they were going to do with it, etc.);2) they are violating the terms of the release (e.g. using the footage in a way or showing it someplace you did not agree to); 3) you did not have capacity to sign when you did (underage; can show you were mentally incompetent at the time); or4) the usage is illegal (to commit a crime, for example).
