Bale, or Bale's people, feeling that he needed to issue a public apology is a bit ridicules, IMO. The event is 6 months old, Bale and the DP have long since worked things out and hopefully Bale apologized to the other people on set after it happened. No one else really needs to be concerned about it and no one else needs to get apologized to, IMO. I think this is just another example of our increasingly judgmental, cult of celebrity society making a mountain out of a molehill.
