President Obama’s trip to Cuba is the first by a sitting president in nearly 90 years. Calvin Coolidge was the last to visit the island in 1928. Talks between Obama and Cuban leader Raul Castro are expected to tackle human rights issues, trade and economic reforms. One industry is keeping a close watch on those talks: Hollywood. No major film studio has shot a film in Cuba since the embargo slammed the door shut in the 1960s. With a thawing of relations, studios are starting to sniff around the island.
