It wasn't a heart-wrenching scene that made Sir cry on set of 's The Hobbit: An Unexpected Journey. So what made him get all weepy?
It was actually the lack of real human emotion that made McKellen break down. According to Yahoo! Movies, the thesp explained how the overuse of green screen technology on the movie caused him to cry:
I had to be filmed separately so I could appear taller than the hobbits and dwarves and I don't like doing that...I just started crying because that isn't what I came into the business to do.
Those who've never acted believe it's an easy job with a great paycheck but that's clearly not always the case. Poor guy.
Jackson's second Hobbit flick, The Hobbit: The Desolation of Smaug, will follow in December 2013, before the trilogy concludes with The Hobbit: The Battle of the Five Armies in July 2014. Let's hope that Gandalf has some company in his next romps around Middle-earth.
