Does anyone know the price of IMDB. Its a one time thing or do you have to pay reapetitly, or should i just wait until i get a gig and they put a IMDB credit. PLEASE ANSWER MY QUESTIONS

Some of the questions you ask can be easily answered by doing a little reading on your part. That said, I will answer this one for you. IMDB is by subscription but if you land a credited role in something, then your name would appear under that film and a very basic page would be created for you. You should probably wait until you "land a gig' before worrying about a page for yourself but being an IMDB subscriber DOES have its benefits. For example, you can look up the representation of almost any actor, find out what films are currently in production, get info on producers etc.
Landing just any gig will not get you credited on IMDB. You first have to have had a principal or credited role in something before they will add you to their database. After that, you can add extra or featured roles provided they meet certain criteria.
So back to your original question, yes the subscription has to be renewed periodically depending on which plan you choose.

thanks
