“Focus,” the Will Smith movie that already was thought to have underperformed, did worse than we thought. Paramount gave an estimate of $19.1 million for Friday- Sunday. But “Focus” came in at $18.6 million. Remember, most of the trades and the prognosticators were putting it at $20, $21 million. Not even close. “Focus” is probably very weak going into week 2. Watch it drop more than 50%. This is not one of those situations where everyone’s secretly gleeful at the downfall of a star. Will Smith is well liked. I’d like to see him score again. And soon. Will, call Roland Emmerich, Now.
