TV comedian James Corden says he is expecting a "bumpy ride" as he prepares to take over as host of a popular US talk show.

The 36-year-old said it is "completely possible, maybe even probable" he could be axed from The Late Late Show within six months.

He will begin presenting the programme on US network CBS on March 23, with Hollywood superstar Tom Hanks confirmed as his first guest. Corden is taking over as presenter from Scottish-born comedian Craig Ferguson, who spent 10 years as host.

He said: "I'm well aware there is every chance it's going to start, no one is going to like it, and it isn't going to work. That's completely possible, maybe even probable, and that it's cancelled within six months.

"It's going to be a bumpy ride, and we're going to be tested in so many ways.

"If the show fails, it doesn't mean I'm suddenly bad or awful. It's an adventure and if it doesn't work, I'll go home and carry on."
