Title Pages: Unable to view expanded role information

When viewing the cast of a particular movie or tv episode, if the cast member has multiple roles in the film or show, the display on the site does not allow any way for the user to see the all the roles the actor has played without clicking on the actor. This requires another request to the server for information that should already be available on the current page.  Would it be possible to add hover functionality to the ellipsis that will display expanded role information without the need to request the actor's page?
