ITV also introduced Martin Brundle's hugely popular gridwalk at the 1997 British Grand Prix, where roughly 10–15 minutes before the start of the race Brundle would walk around the grid interviewing drivers, team personnel, celebrities and whoever else he could find. Brundle had elected not to commentate from some races such as the Canadian Grand Prix in 1997 where he raced at Le Mans and missed the race in 1998. He also elected not to attend the Hungarian Grand Prix on several occasions. When Brundle was absent, different people would stand in the commentary booth, including Derek Warwick, Jody Scheckter, Anthony Davidson and 1996 champion Damon Hill.
