Hello
I'm working on an article about "Batman the Movie" from Ocean.
So I confirm that originally the game was developed on Amiga. The ST images between levels are indeed a plus that the Amiga version does not have.
The game window is a bit smaller on Atari ST.
Originally the batmobile level was different between the ST and Amiga version. The first advertisements and some previews in magazines show this difference. The view on ST was on the side like level 2 on Total Recall or the view on Amstrad CPC while on Amiga the game was already seen from behind.

The bottom belt was not the same either, the graphic designer confirmed having redesigned it
Then the ST version was upgraded, but I don't know why these levels 2 were different between ST and Amiga and why they managed to do it on the Atari ST.
I wonder if there will still be a preview of this ST version with this side view, I searched but found nothing... too bad
