The 2011 version of "The Three Musketeers" (the version with the airships) is not a good film by any stretch of the imagination. I found it highly entertaining, but I certainly wouldn't call it 'good'. (That said, the makers of musketeer movies are always up against it - the Reed/York version is definitive.)
Anyway, much as it's not a good film, that version does have a number of good lines. IMO, the best of these is from Cardinal Richelieu as he finds Rochefort practicing his swordsmanship:
"The wonderful thing about fighting an imaginary opponent, Captain Rochefort, is that he is always greatly skilled, yet easily defeated."
I can't think why the latest book I've finished reminds me so strongly of that particular comment...
