James Corden feared 'The Late Late Show' was going to be a disaster in America.
The 38-year-old star took over hosting duties of the talk show from Craig Ferguson in March 2015 and although it has been a huge success for him he was very nervous that American audiences wouldn't appreciate his British sense of humour and interview style.
He shared: "I wouldn't have moved to America and taken on 'The Late Late Show' if I were a pessimist but at the same time it would have been very naive of me to speak publicly about it being successful before it had even started.
"I decided that the best thing to do was to say it would be a disaster. If it hadn't of worked I could say, Yeah, well, I did say that."
The show has proved to be far from a disaster with 1.28 million viewers a week and millions of YouTube views for his feature 'Carpool Karaoke' which has seen music superstars such as Adele, Britney Spears and Justin Bieber join him behind the wheel for a sing-a-long.
Even though he is riding high in the ratings, the former 'Into the Woods' actor is already thinking about what he can do next as a project.
Corden - who has two children, son Max, five, and 23-month-old daughter Carey, with his wife Julia - told Radio Times magazine: "My biggest worry is that I'll run out of time - I really want to make the most of the time that I have. When you're lying in your death bed, you're not going to think, 'Oh I wish I'd made one more TV show ... I try to remember that all I've really got is right now. Everything that's behind you is gone, everything in front of you is unknown, so if you try to do your best in the time that you're here, then you will have a good and successful life."
