Todd was a supporter of Second World War commemoration events, particularly those associated with the Normandy landings and No.617 ("Dambusters") Squadron, RAF. He continued to be identified in the public consciousness with Guy Gibson from his portrayal of him in the 1950s film, and attended 617 Squadron anniversaries up to 2008. He narrated a television documentary about the Squadron, and contributed forewords to several books on the subject, including "The Dam Buster Story" (2003); "Filming the Dam Busters" (2005); and "Bouncing-Bomb Man: The Science of Sir Barnes Wallis" (2009).
