Battle of Britain Day is commemorated in England on September 15th and in Canada on the third Sunday of September. Both dates coincide this year, making it the perfect time to review the dashing style of Canadian actor Christopher Plummer’s portrayal of a Royal Canadian Air Force officer in Guy Hamilton’s 1969 war epic, Battle of Britain.

Plummer stars as Squadron Leader Colin Harvey, whom we meet while commanding Squadron No. 188’s retreat from France in May 1940. After finding out the following month that he’s been assigned to a position in Scotland, he joins his wife, Section Officer Maggie Harvey (Susannah York) at a country pub in Denton to discuss the opportunity. He enjoys a “large Scotch”, perhaps to get into the spirit of his upcoming command, but it’s hard for him to feel spirited rather than disappointed when he learns that Maggie can’t apply for a job near him, responding to her with “What have we got? What the hell is this? Is it a marriage or a flaming Air Force committee?”

Colin’s new command distinguishes itself in battle after Adlertag (“Eagle Day”), the first day of the Luftwaffe’s attempted air invasion of the United Kingdom, though he and Maggie fail to reconcile before he’s badly burned during the climactic air battle over London on September 15, 1940, 84 years ago today.

The resulting British victory that day likely prevented a full-scale German invasion of the UK, prompting Prime Minister Winston Churchill to famously declare:

Never in the field of human conflict was so much owed by so many to so few.
