Most sources point out that the Sorcerer title was only used in the US, which suggests that the poster should be printed in the US and distributed elsewhere.
Title wise, I am still sleuthing to see the working title used in Singapore at that point of time, so I shall need some time. Personally I won't be too surprised if we used the Sorcerer's title. A more recent example I can think of is Disney's Zootopia. To my knowledge, the title Zootropolis was used in certain places, but Asian countries such as Hong Kong, Japan and Singapore used the US title Zootopia instead.
