Movies are classed 'Coming Soon' (ie: showing on your Coming Soon page) by having a release date in the future. A movie's release date can be set in Veezi/Vista, this release date pulls through to your website.
To hide a movie from your coming soon page, you have three options:
Login in to your website admin.
Go to MOVIES, select the movie you wish to change and click EDIT.
In this screen, you will see an option to set a release date.
Change this to the desired date, and uncheck the tickbox 'Release Date - Receive updates' (this will happen automatically after completing step 5).
By unchecking this tickbox, you have turned off updates from Veezi/Vista (for the release date field, for this movie at this location), so it won't be overwritten on next import.
