There was an interesting article on The Wrap this morning discussing what the guilds are doing to prevent IMDB from listing birthdates on their website. Even though IMDB is not scientific, a lot of industry people rely on it as a source of information about people working in Hollywood. The biggest problem I see is for actors who play young, but in reality may be a bit older. I've actually had a casting director say to me that if an actor is listed as over 21 on IMDB, he would not bring that actor in to read for a role that is under 18. If an actor who is over 21 truly looks 16, why shouldn't he have the right to audition and possibly play that role? Let me know what you think about this in the comment section.
