Upload subs for movie with no IMDB link

Hi,
I'm having trouble uploading English subs for an Iranian movie that has no IMDB link. I tried leaving the IMDB line empty or adding a link to another site - it doesn't let me do that, when I press "Create", it sends me to the page for uploading subtitles for "An American Werewolf in London" , for some reason. Any ideas how to get over that hurdle?
