Episode VI - Blue Harvest

If you heard that 'Blue Harvest' wanted to film in your location, you wouldn't pay much attention to it – and that was exactly the point.

In order to avoid paying an eye-watering sum and prevent the possibility of leaks, George Lucas opted to call his movie 'Blue Harvest' with the tagline "Horror Beyond Imagination" when he was scouting for locations for 'Return of the Jedi'.

The trick was used in California when Lucas wanted to use the Redwood National and State Parks to film scenes on Endor.
