McConaughey bought himself a motorcycle for the movie.

While Hudson was prepping with Wintour, McConaughey was doing some research of his own.

In an interview clip from "E! News," McConaughey said he bought a motorcycle because his character, Ben, drives one in the film. 

"I wanted to get comfortable on a motorcycle because I've seen too many people ride motorcycles or someone ride a horse in films where I'm like, 'You don't really ride a horse. You don't really ride a motorcycle,'" he explained.
