I think The Tudors TV show is famous for taking liberties with history.
I believe in one episode someone was shown shooting a pistol that was not invented until about 200 years later.
And many characters and events have been changed, altered, adapted, merged etc. to make the series easier to follow or more exciting.
I see it as nothing more than a soap opera, using the Tudor characters to "hang" the stories off.
See the Wikipedia enter here, under "Departures from History" to see how much they have changed actual history.
