'Melancholy' - noun, a feeling of pensive sadness, typically with no obvious cause or reason.

Or, a word that Jake Gyllenhaal will not allow to be mispronounced in his presence. During the numerous interviews that actors and directors have to do at festivals like Sundance, you probably start to pick up on little verbal ticks and quirks of people.

If it happens to be 'melancholy', however, Jake Gyllenhaal won't let that slide. He doesn't care if it's in the middle of an interview with industry bible THR or not and you're 'Velvet Buzzsaw' director Dan Gilroy, he will stop tape and call you on it. And he'll point out that this isn't the first time he's had to correct you.

Why? Because he is Jake Gyllenhaal, Pronunciation Adjudicator. And that's pronounced 'ah-judi-KATE-orr'. The 'D' is silent.

Take a look.
