Earlier this year, McConaughey went into detail about the experience, saying, “The audition went really well. Well enough where when I left I was being glad-handed and slapped on the back, like, ‘this is what we’re looking for. You’ve got it.'”
Later on, James Cameron commented on the events, saying, “Matthew read for the part, and then we met Leo. Leo came in for an interview, and I had this weird thing: I looked around the room and every woman from the building was in the meeting… the accountant was there and the female security guard, so I thought ‘maybe I better cast this guy.'”
