Reporter: Was Eddie Murphy serious off camera?
Marsha Thomason: Eddie and I laughed a lot but he is quiet and reserved. There is definitely a pressure for funny people to be funny. People want them to perform all the time. But we got on well.
Reporter: Do you believe in ghosts?
Marsha Thomason: I have never seen a ghost. But yes I believe because I know too many people who have had experiences. When I lived in Notting Hill, I shared a flat with a mate who was convinced that there was a presence in our house.
Reporter: Is America now your home?
Marsha: I have a house in London and a place in LA and I'm bouncing between the two. It's very nice because I fly first class now and that makes the world of difference.
Marsha: I find that casting in the US is very much a color coded system.
Marsha: A well known director wouldn't take the chance on casting me for an American role after he discovered that I was English.
Marsha: I enjoy the reaction I get in the USA when people discover I have an English accent. They don't expect that and it's kind of a kick.
Marsha: When I am on the plane and turbulence kicks in I can't abide it. I feel like we are all going to die and it takes everything in me to stay calm.
Reporter: Which actor/actress/performer did you have a childhood crush on?
Marsha: Anybody that knows me could answer this, it's JT-Justin Timberlake, any day of the week!!
Reporter: What TV show from your childhood would you want to guest star on?
Marsha: It would be fun to be a guest on Scrubs. I looove that show!!
