Angry outbursts never look good, but we’re going to have to call this one as fair play. Or at least not obviously foul.
A true gentleman would have exercised a little more politeness, but frustration is just a byproduct of passion, and passion is always a good thing. Hundreds of actors would have let a few slips from the crew slide, and in the process accepted less from the movie and less from themselves. Much as the gossip press wishes it were otherwise, there’s no shame in caring about what you do.
Even if it means getting a little unkempt.
