Reminds me of a Jamaican film I saw decades ago. With the thick accent they added subtitles to what was an english language movie at least in name. :)
Funny Australian video from a while ago: Why do I need subtitles?
Supposedly in the original print of Mad Max the Australian actors were incomprehensible to American audiences, and so it was dubbed over in American=ish accents.
Might just be an old wives tale
