From my research, the phrase talent is everywhere, but opportunity is not was possibly first made popular by a book and a documentary film concerning women’s rights across the world.

The film was released in 2012 and the book with same short title was published in 2009.

The authors of the book were involved in making the film and the book included the following text, later reworded within the film to make the phrase:

“The main factor that separates me [said Harper McConnell, USA] from my friends here [in west Africa] is the opportunities I was given as a first-world citizen, and I believe it is my responsibility to work so that these opportunities are available to all.” (Kristof and WuDunn, 2009, p103)
