I am a media student in the KHM-Academy of Media Arts (Cologne) and in the moment about to commence a project about Slaves Ships (vessel).

The project is related (between other things ) with the famous poem of the poet Heinrich Heine: Sklavenschiff (Slave Ship).

What I am looking is for films that deals -at least in one part of them- with this subject.

Something that will be great to find, are silent movies...

I already have a little list, but I just begin. 

By the way,  I am trying to find the Tay Garnett, "Slave Ship" (1937).
