They have this feature in Asianwiki so I often find myself going to Asianwiki to see what the actual characters look like in the drama. I think with this feature, it's easier to visualize the feel of the drama before deciding to watch it. Also, sometimes the profile pictures of actors are not recognizable or look very different from the actual actors. Hope this feature gets implemented considering how these pictures influences our perception about the dramas.
EDIT: I see that we have the fictional character profile page. Perhaps we can implement this feature by allowing users to upload the character's profile picture on that page in place of the actor's profile page. In the drama's cast section, the character's profile picture if available should be shown. This way, the user will have to create the character's profile page.
