Are you expecting people to sometimes walk up and examine the poster at 
close hand or just look at it from a distance? If it is only to be viewed 
from a distance, then a DPI of 100 or even just 50 is probably acceptable. 
Normally the guiding principle is that posters should have a DPI of at least 
150, but what you're making is definitely not a "mere" poster.

Also, does your image have detail that requires a high DPI to show it off 
properly? If the image is photorealistic, and the image has some "shortcuts" 
where detail have not been created in an extreme level, then a higher DPI 
might just reveal this fact even more and make the image seem more crude. On 
the other hand, images where simple shapes and textures are an integral part 
of the style will often look fine when blown up to a high DPI, though it 
still might not be necessary.

Naturally, if you're using focal blur, or have any other valid reason that 
the image would naturally be slightly blurred, then a extreme resolution 
seem unnecessary.
