The 34-year-old actor said when the cast boasts of star artistes, one often ends up thinking how everything will fall into place, reported The Independent.
"I don't feel like a star, I just happen to lead a TV show. Everyone was just up for having a good time. It felt like no-one was there to prove anything...
"I always feel that way about any project. If you have 'stars' involved - film stars, movie stars, TV stars - you're always concerned with what that will do to the dynamic of the project," Cox said.
