The exclusions weren't working because you were using $ESCINFO[] which encases the string in quotation marks ""
$ESCINFO is only for scripts/built-ins which might get confused by a label with commas in them and think that it is splitting an argument. Commas don't matter for a plugin because the path is passed to the plugin as a paramstring.

I also don't know why you were building the lists based off your hidden detailed item. Using infolabels from the detailed item would slow down your info because you are waiting for that to build first, when library items will already have ListItem.Director / Studio / Genre etc.

It would be best to use a variable to check !String.IsEmpty(ListItem.Director) and use ListItem.Director first, then only fallback to the detailed item if no director is available.
I don't use a hidden detailed item to populate cast or a separate cast-list call. I just use the built-in id="50" class list in dialogvideoinfo. So that's why mines much faster - because I'm not doing any separate look-up.

In the detailed item, I fill the default cast list in addition to the individual properties. Because the custom window calls the info dialog on the detailed item, then the default id="50" list will be filled with cast. The only time you won't get cast is if you are using a TMDbHelper list as a widget because cast info isn't available for lists (e.g. Popular Movies etc.). However, if any list item already has a detailed version cached, then I will merge the info. 

@jurialmunkey, thank you so much for your help and the explanations.

I will go back to the drawing board with my cast panel to use the info from container 50, since with what you mention, this container will have the cast for online or local items. I imagine that, while a bit slower, I can use a custom cast panel that gets the info from container 50, so I can have my custom onclick and allow the user to search either online or locally for the person's info.

Thanks again!

No worries.

What I would probably do is still have the additional cast list from the detailed item but only show it if the id=50 cast list has no items. You may as well use the additional cast list since you are going to be getting the detailed item anyway. That way you get the best of both - quick loading if it exists and the detailed look-up if it doesn't.

You could use similar variables for your movies featuring cast list to check if you have something in id=50 and use that if available, but fallback to the detailed item if not available.

@jurialmunkey, thanks! I sort of did that, using the same custom panel with content items from both container 50 and the details hidden list. The items are shown based on visibility conditions.

I tried using two different cast lists (I don't know if this is better than my approach?), but then the navigation between custom info lists and cast broke and I could not figure out how to fix it.

What I have now works, except that on first use with an empty cache, I don't get any cast at all for the first movie I try, it seems that the plugin takes a little bit of time to fill the details hidden list, and my busy loader image is not even showing. I am not sure how to fix this or why it is happening.

Any additional pointers will be greatly appreciated!

Bart
