Miles Teller (star of the upcoming "Fantastic Four" reboot) is an aspiring jazz drummer in the new trailer for "Whiplash," a Sundance favorite that earned raves earlier this year. But unfortunately for Teller's character, Andrew, he has to deal with the most terrifying teacher ever, in the form of Terence Fletcher, played with ferocity by J.K. Simmons.

Terence is verbally and physically abusive, going so far as to slap Andrew across the face in front of a room full of musicians, then taunt him for crying by calling him a "worthless pansy ass." Just when you think Terence can't get any worse, he continues on a campaign of psychological torture so discrete that his words seep into Andrew's very being as the young drummer vies for Terence's approval.

"I want to be one of the greats," Andrew says as he justifies Terence's behavior -- and putting up with it -- while his personal life and relationships crumble around him.

"There are no two words in the English language more harmful than 'Good job,'" Terence declares to Andrew toward the trailer's end. We have a feeling that Andrew may unravel completely in his pursuit of hearing them anyway.

"Whiplash," written and directed by Damien Chazelle, is set to screen at the Toronto International Film Festival later this year. It opens in theaters on October 10.
