The Arthur star, who currently lives in Los Angeles with his 26-year-old wife Katy Perry, may be happy in the US for the time being - but not when he has kids.
When asked if he wants to return to the UK, he said: 'I secretly want to do that. I have a fear of hearing my American children speak to me in American accents.'
Although he thinks it would be hard to persuade California-raised Perry to move.
Russ, 35, added to Seven magazine: 'I'm sure I can sell her Great Britain on some level. The Cotswolds, people seem to be up for that don't they? Stone-walled cottage.'
