7. Johnny Depp
Johnny Depp used to sell ball-point pens over the phone. Yes, that’s right, ball-point pens over the phone. They weren’t any ball-point pens however, they were personalized pens with the person’s name printed on them.
No one he called wanted to be called. He used that opportunity to work on different fake voices and personas to help relate to the people more. Little did he know that that training would help him later in his life for roles like Captian Jack Sparrow and The Mad Hatter.
