UPDATE: According to HBO, Hoji Fortuna has NOT been cast. At least, not as anything other than an extra. A featured extra with one or two lines, at most. So definitely not Brown Ben Plumm and probably nothing at all.
Fortuna has worked mostly in African and Portuguese cinema up until now, although he did have one brief appearance on US TV in the short-lived series Pan-Am.
Fortuna has been teasing on his Twitter and Facebook that he will be heading to Croatia to film sometime soon. That narrows down his role to one in the King’s Landing or Daenerys storylines. Speculation points to Brown Ben Plumm, a sellsword captain who Dany encounters in her travels. There are a number of other more minor characters that Fortuna could play though and there is always the chance that he is a newly created character.
Winter Is Coming: I’m really hoping he is Plumm as he matches the image I had of the sellsword almost perfectly. What does everyone else think?
