VIDEO : Matthew McConaughey Acted With A Real Tiger And His Kids Are Learning Portuguese

Matthew McConaughey and wife Camila Alves are taking their three children and heading off to Brazil to visit her family for the holidays. To prepare, the Sing star says his kids are brushing up on their Portuguese. In the intense drama, McConaughey's character has to pet a tiger in order to seal a business deal with some shady investors. While some stars would have insisted on CGI tiger for the scene, director Stephen Gaghan decided to use a real tiger, which meant McConaughey's trepidation in the scene wasn't something he had to fake.
