How to display Cast Actor image on custom page?

Hello

I have plan to create my custom Video View page similar Plex Web-page.

Here is Plex Web-page for casting I want.


Yes, I know on Kodi how to display this (Conext Menu) on Kodi Skin - DialogVideoInfo.xml.
However what I want is, I will have movie list and cast at same page on my custom view type.

This is what I want to


This is current my movie list code I have..

<control type="list" id="900">

...

<itemlayout height="291" width="212">

...

     <control type="image">

                       ...

                        <texture background="true">$INFO[ListItem.Art(poster)]</texture>

                       ..

     </control>

 <focusedlayout height="291" width="212">

   ...  

     <control type="image">

                       ...

                        <texture background="true">$INFO[ListItem.Art(poster)]</texture>

                       ..

     </control>

Actually, I don't know how to pull casting actor image from selected movie
When I am searching this, there is some way to use TMDB API or TMDB.helper script. But I don't know how to use it.

So,if you know any same concept skin what I want (Video list + Movie actor with same page), please let me know. I will look into. Or if you have any tip on this, it would be help.
Thank you
