George Ezra was ''nervous'' working with Sir Ian McKellen.

The 21-year-old musician admitted that he was anxious about acting alongside the 'Lord of the Rings' star as part of his music video for his single 'Listen To The Man'.

Talking to the Daily Mirror, George said: ''It was nerve-racking trying to act beside him. I'm not an actor and he's phenomenal.''

However, the singer-songwriter did joke that the legendary actor was a little off-putting because he couldn't resist hogging the camera.

George said: ''He just keeps butting in and p***ing me off and stealing the camera. In real life, I hate being on camera but in the video, that frustrates me.''

The soulful singer then invited Sir Ian to come to his next gig in Shepherd's Bush, to which the 75-year-old actor quipped: ''Is there any chance you can play closer to Limehouse?''

On Wednesday (15.10.14), George made reference to an iconic quote from Sir Ian's 'LOTR' character Gandalf. He tweeted: ''You shall not pass.''
