A bit of constructive criticism If you don't mind.

You forgot:
The Year
The Source

Way more important than the actor's names (IMO that flat out is a waste of space in a filename).

Try using group tags and including:
Title.Year.SOURCE.CODEC-Ripper

First three parts are the most important,
Title, year and source.

Out of them three you only included one. I think the removal of details come from when the user is forced to edit the file anyway, so you should strive to keep them neat, condense and to the point. If there isn't stuff that people are going to remove, they tend to leave the tags... or so I think that's what I've noticed from using p2p.

Avoid brackets of all kinds, avoid infact all forms of punctuation particularly none standard ones. IMO info that just flat out isn't needed in a filename is actor and director, you know this anyway, if your insterested in the movie via search, you know the movie, if you find it in a forum, that's the place to put the info... its just filename bloat.

From title and year, you can find every scrap of info on the movie, simply by going to IMDB.

Source is most useful for people doing blind emule searches, shows them what to expect.

Codec is kind of pointless, but its nice to have their.

Proper is good to show that the version is the best available.

Cut status is a good one, but only put in if the movie is well known for having many cuts, or it is censored but not commonly known (the latter promotes more hands trying to track down an uncensored version ).

The ripper name comes in after, and if you got the above, and nothing else, I've noticed it hardly ever goes.
