Where can i find high resolution film posters?

[joko]

I want to find high resolution film posters for casablanca or top hat, because I want to paint a picture with my brother and his wifes head on them. all the ones i have found are very small and lose much detail when i try to enlarge them.

I want to print it out to refer to it while painting (at least A4)

anyone know of any sites i can try?

thanks

Do you require better resolution than this?

How about this one.

WOW! thanks kempie! hopefully they'll be just right.

I tried that site, the Top Hat ones don't link to a larger picture, although the casablanca ones do (!)- do  you know of a way?

Thanks
