Most of the Oddworld merchandise that has come out so far is promotional only (apart from the Exoddus stuff). By this I mean that it is used for gaming shows (E3, Game Developers Conference, etc). Or you have to be an Oddworld Inhabitant to get it (i.e. with the SoulStorm Brew bottles).
As for if there is any movie, I'd love to see a huge Oddworld standee promoting the movie. The only trouble is I'd have to hope I get lucky and get to take it home with me.
This did happen for the Final Fantasy movie... I was at the last session of screeing in the city, and when it finished I asked about the movie posters (which I got some). Then I jokingly said to the guy "imagine if you could get that display", and he said if I can get it out of the theatre I can have it. So the next day my dad takes us in with the station wagon, but the movie display is so HUGE that it won't fit in the vechile. So here's me, my dad and my mum on one of the main streets of Melbourne dis-assembling this movie display! Crazy stuff!
It's now all folded up as it's so huge.
But I do have my full size Munch's Oddysee instore display which I got from the US in my room. It's one of my best Oddworld things!
