Because the previously shared workflows for IMDB-integration didn't work anymore I made my own. This is my first publicly shared workflow and this is also my first python-script. Probably things could have been programmed better, but it works for now.
So its not really fancy, but I think its workable, as long as IMDB doesn't change the API. Hope this workflow is some use for you all.
