I am indifferent on this, important is only performance of studs and them to respect the girls they work with, be professionals.
However, fans have to be aware that Prague indeed as opposed to Russia has some BBC work migration, but black actors are still just really limited and thus very well catered for by their studios. Hardly you see any BBC actor working for different studios at the same time. Freddy Gong did it earlier I think, but almost no-one else. Studios try to have their BBC exclusively. AGO would have to invest a lot of money and care to build a working BBC team, feasible alternative could be to fly in 1-2 BBC from USA for limited time and shoot some new line scenes with a mixed studs team.
Question is has he this resources, or shouldn't he just better concentrate on doing better what he already is successful with, improve camerawork and lighting for instance.
