His voice sounds exactly the same in real life.

Matthew McConaughey is very kind. I tried to take a photo of him (on my boss's orders) but I didn't want to, so I was trying to use my phone's reverse camera. He noticed what I was doing, and that I was having trouble, and told me, "You can just do it." So now I have a photo of Matthew McConaughey laughing at me. It's fantastic. Also, his voice sounds exactly the same in real life.
