Alcon Entertainment obtains comedy pitch “Back to America”, an idea hatched by comic-actor Martin Lawrence:

The comedy centers on a working-class man from Queens who discovers he is heir to the throne of an African country and travels there to claim his birthright.

Talk about ‘similar but different’? Here’s the logline to the 1988 Eddie Murphy movie Coming to America:

It is the 21st birthday of Prince Akeem of Zamunda and he is to marry a woman he never saw before. Now the prince breaks with tradition and travels to America to look for the love of his life.

And here’s the logline to the 1991 movie King Ralph starring John Goodman:

When an accident obliterates the British royal family and most of its branches, a desperate geneological search discovers the next king: Ralph, a sleazy American lounge singer.

Blend those two and you pretty much get “Back to America.”
