There is a longer title sequence on the extras. It just shows more planets being destroyed, derivative of Men in Black II, rather than seeming like an arbitrary event. Besides, the first movie had no title sequence at all, so one would indeed dream of actually having one, as if one were watching a superhero movie.
And in regards to the wedding, I think he meant all the supposed cancelled wedding attempts in the past that aren't elaborated on, not this particular wedding in the movie. Again, it looks like an isolated event.
Give the guy a break. He directed TAXI.
