"I remember auditioning for The Lord of the Rings and going in and not being told that I needed a British accent," the actor tells The Hollywood Reporter. "I really do remember Peter Jackson saying to me, 'You know that you have to do this in a British accent?' We heard back it was literally one of the worst auditions."
Not that it put a damper on Gyllenhaal's career.
After all, the guy has gone on to do some pretty impressive work in such films as Brokeback Mountain, Zodiac, End of Watch and the recent Prisoners, for which he's being viewed as a possible Oscar contender.
Of course, Middle-earth isn't the only movie world Gyllenhaal has tried to enter.
Meanwhile, Gyllenhaal is currently hard at work on his upcoming film Nightcrawler. He told E! News last week at the Hollywood Film Awards that he has lost "somewhere around 20 pounds" for the movie.
Let's see Frodo do that!
