“We went to Colombia, and the mail system doesn’t really work very well,” the 36-year-old actor said. “It’s completely unreliable. I received a letter from her, and I realized that from the tone of it and things she was saying that she hadn’t received the two letters that I sent before.”
In the film, Charlie plays 19th-century explorer Percy Fawcett, who is an absentee father. So he decided to go full Method and stop writing letters all-together.
“Which obviously makes me sound like a total bastard, appropriately so. But I was very apologetic,” Charlie continued.
“I had the benefit of shooting in Colombia, where they have rather lovely and somewhat cheap emeralds,” Charlie added as a way to make up for the blunder. “My girlfriend is a jewelry designer, so I was able to come back with an appropriately sized gift. It didn’t remedy all of the trouble I was in, but it got me halfway there.”
The film hits theaters on April 14.
