If you're in a motion-capture studio, you have spherical, reflective markers, which are picked up by cameras that emit infrared - it reflects it, and then the cameras pick up the data.
Oftentimes, when you have a huge studio film and you have big names attached, they like to keep attaching big names.
Whenever I go into the studio, I'm like, 'Guys, we're probably not going to get an uptempo out of this!'
I really believed in 2 Chainz, I really believed in Future, and I was going to the studio with them every single day.
One of the more surreal days I've ever had in the recording studio was Martin Fry teaching Hugh Grant his old dance moves. Showing him how to do the hair-flip and the point, and all these sort of trademark moves of his.
