Here is a trailer of a French language film that came out in November last year.
Also, Bubblebustin cited a National Post commentary:
Our new Prime Minister is so much Stephen Harper’s antithesis — young, open, charming — that it’s easy to ignore the fact that he is the personification of old world power, or the closest thing we’ve ever had to it in this country.
Yet even the fact that his ascension marks the beginning of our first familial dynasty in federal politics is treated like a charming footnote, instead of what it is. It’s no coincidence that Trudeau’s nickname before assuming office was the Dauphin. Margaret Trudeau is now marked with the rare public distinction of being both a mother and a wife to a prime minister, like some kind of democratic dowager queen.
