who is the light-skinned black up dancer/brother with the cornrows in the Rihanna video "Where Have You Been..." The IMDB website doesnt list any of the backup dancers as "cast". Does'nt list them at all?? That should be corrected. But I'm not sure how to do that.
Jim, often the music videos doesn’t have real credits (of course there are exceptions) - or at least MTV and other TV channels doesn’t usually broadcast versions that (possibly) include credits. Same thing with many (if not ”most”) music videos on Youtube etc.
So yes, additional research is usually needed if you want to credit background dancers or ”not-that-known” actors and extras that appear in the music videos. Sometimes even the research is not enough.
