@Sidebysws9 - by controversy do you mean that people are critical of the accents delivered by the actors (in general or KBA’s in particular) since the film release or surrounding the casting of non Jamaicans at the expense of Jamaicans?
Two separate issues but understandable that people might feel that a Jamaican should have played Bob and at the same time would have got the accent.
I think it is reasonable to expect people to do a good job of accents generally - if you’re British you probably cringe at a poorly done British accent.
It is even more important if the person you’re playing is known for their speech. Bob’s life was largely about the music and the message, he was Jah’s messenger, and it would have been a disaster if his accent was too off mark. The family knew that from the get go.
Arguably, although still important, the delivery of Rita’s was not as crucial and was perhaps more forgivable.
I’m not even aware of how much I speak patois daily at home but sufficient enough that my Dc understand what I’m saying. Their spoken patois is the Cool Runnings variety though.
Not sure if Lashana’s parents are British born and how much she would have heard/spoke patois at home but it doesn’t matter, it wasn’t her first tongue.
Lashana would have had to work on the accent too although you would have thought that she had a head start.
