actors and crew should have a field to fill in alternate names, because some people are known by multiple names and this would cut down on how many extra profiles there are as well as ease searching for actors.
example: Dwayne Johnson is also commonly known as The Rock. or Thandie Newton is often times credited as Thandiwe Newton. eastern actors like Zhang Ziyi are often credited in the west as Ziyi Zhang because in many eastern languages the surname comes first before the given name.
