WHY did he say it?
1 he knew it would be a big deal but figured it would create interest and controversial publicity for the movie (the 'no such thing as bad publicity' thing) as his 'Taken' type action movies are getting abit tired now/could use a boost?
2 he figured it wasn't that much of a big deal as so long ago and just said it as that was what he drew on in preparation for the revenge based role?(how wrong he was)
