At the 2000 French Grand Prix, the usual ITV commentator,
Murray Walker, was unable to commentate. This provided Mark with his first chance to show off his commentating skills. During 2001,
Murray Walker, did not attend the fly-away Grands Prix (races outside of Europe). James filled in, commentating alongside former F1 driver,
Martin Brundle. Following
Murray's retirement from commentating, James was offered the full-time position on ITV, and has commentated every race since the 2001 United States Grand Prix.
