Bill Nighy is amazing
Though I've linked to this video before, I simply must do it again. Even if you've never watched Love Actually (though, as I wrote yesterday, you really should), you will be amazed by Bill Nighy as aging rocker Billy Mack in this video. The video as a whole never appeared in the movie, which showed us only snippets, but Richard Curtis was wise enough to make it anyway and use it as an extra on the DVD.
I can't get a firm count of all the videos Curtis is lampooning here, though "Addicted To Love" is clearly the most prominent.
Watch Nighy's hands, which he uses more oddly than any actor I know.
Enjoy.
