Just one big happy Zamundian-American aristocratic

Prince Akeem goes to America to retrieve the bastard son he never knew he had, so the kingdom can have a heir to the throne. Coming to America was released already in 1988 and conveniently the major bulk of the cast (Eddie Murphy, Arsenio Hall, Shari Headley, James Earl Jones, John Amos, Paul Bates, Vanessa Bell Calloway, Louie Anderson) appears in the predecessor as well. Unfortunately eighties sense of humour and the feeling of them times too.
