Brad Pitt has his goatee because he is filming a move based on the book "The Lost City of Z", about the famous South American explorer Percy Fawcett.
Here is a link to the book on
Amazon:

I am currently reading the book. Very, very interesting. Fawcett was convinced that a huge, lost civilization was hidden away somewhere in the Amazon basin of Brazil. Fawcett was famed for his ability to endure hardships, etc, and he had several times gone into the Amazon basin to search for his lost city, only to emerge months later to report failure (although he did extend our knowledge of the Amazon area).
He and two companions (including a son of his) went into the Amazon one last time in 1925. We are still awaiting his return (indeed, several expeditions went looking for Fawcett in the decades following, only to never return themselves; the largest expedition supposedly had 1,000 men, and never returned).
