Answer: In his recent book 'Kevin Smith's Secret Stash', Smith states that he experienced "true darkness" working with Bruce Willis. According to Smith, Bruce Willis does not enjoy making movies. Smith accuses Willis of being lazy and accounts several stories of the two having creative differences on set, including Willis being angry that Smith allowed Tracy Morgan to improvise dialogue. Willis also apparently took issue with Smith contradicting him in front of the crew. For his part, Willis has only vaguely commented on the animosity between the two, calling Smith a "whiner" in one interview.
