Goodbye, Gandalf

There's a light at the end of the tunnel, and it's bittersweet. Peter Jackson is nearing completion of principal photography on his epic The Hobbit trilogy, and he just wrapped Ian McKellen for good in his role as Gandalf, which he famously originated in last decade's The Lord of the Rings trilogy. In a touching post on Facebook, the Oscar-winning director bid goodbye to his dear friend.

"Seconds ago we finished our last shot with Gandalf. The end of an incredible adventure that began in 1999. I'm feeling very sad right now," writes Jackson.

Getting through a single movie is an accomplishment not to be taken for granted for any actor and director. To journey through six epic films is a herculean feat, and the complex emotions both artists must be going through are evident in their expressions.
