Peter Dinklage
Before Dinklage became Tyrion Lannister in Game of Thrones, he was just a normal guy who worked an office job. He liked to party with his pals, and he was the frontman of a punk band called Whizzy. He used to work 9-5 and hit the bars right afterward, somewhat similar to his character in Game of Thrones.
From Data Entry to Dragon Taming
Dinklage worked at a company called Professional Examination Services. He didn't, and still doesn't, know what his company did. Evidently, he "just plugged information into a computer," and called in sick every Friday because he would go out with his friends on Thursday.
