> I can think of no memorable visuals despite having seen it on IMAX.

Off the top of my head:

* The arrival of the Imperial delegation for the 'signing ceremony'.

* The fight training sequence.

* The view from behind Paul's head, with the Gom Jabbar at his neck.

* The opening of the doors on arrival at Arrakis.

* The starting of the ornithopters' engines.

* The found hunter-seeker operator.

* The cockpit view dive of the ornithopter.

* The view of the spice harvester being swallowed from the ornithopter ramp.

* The bombs penetrating the ship shields and the contained explosions.

* Paul and Jessica on the top of the hill, viewing the aftermath of Arakeen.

* The wide dining room shot with the Barron on the left and the Duke on the right.

* Paul 'tripping' in the tent.
