ACCLAIMED actor Sir Ian Mckellen will be appearing on the BBCs hit television series Extras tonight.

The star of hit films such as Lord of the Rings, who is also a former Bolton School old boy, will be appearing as himself in the show devised by Ricky Gervais.

Commenting on appearing in Extras, on at 9pm on BBC 2, Sir Ian said: "It was a thrill to be so close to a comic actor in his prime but nerve-making too.

"So I was somewhat relieved when, after one of my lines, Ricky Gervais guffawed so loudly that we had to start the scene again - and then again, as he laughed some more.

"This was reassuring and alarming simultaneously. I mean, if he ever stopped laughing would it mean I was no longer being funny? I said I wished he could control the open expression of his glee as I wasn't sure I could be much good if he kept interrupting."
