(2.3) When I want to talk about actor in movie , to where should I post it?

The decision of where to post this type of articles requires a
judgement call. The poster will have to decide the focus of this
thread.

*  If your main interests are about the acting ability of actor <X>
   as illustrated in movie <Y>, and possibly other movies that
   actor <X> has been in as well, you should post it to rec.arts.
   movie.people.

*  If your main interests are about how actor <X> has influenced
   the quality of movie <Y> and would like to discuss things
   specific to movie <Y>, you should post it to rec.arts.movies.
   current-films or .past-films.

*  If you cannot decide on the focus of your post, maybe you
   should just post it to one of the *-films group.

There is no need to crosspost. Most people subscribe to more
than one group so they will see your post. Please also refer
to the standard Netiquette described in Section One, Question 3.
