Rupert Grint's 'CBGB': Check Out The Latest Very NSFW Clip

The R-rated clip takes you inside the sex, drugs and rock 'n roll of punk's most famous club.

A new exclusive NSFW clip from the historical rock drama "CBGB" has everything you expect from the start of New York's punk scene: sex, drugs, and rock 'n roll. Rupert Grint and Justin Bartha stand in for the Dead Boys, so there's the rock. You have to imagine there's some drug use going on, but the sex is pretty hard to miss.

During a set at the iconic club, an unruly crowd member takes the song title "Caught With the Meat in Your Mouth" a little too literally.

As on-screen bandmates, Grint and Bartha got to know each other pretty intimately. Aside from the very private moment that takes place on the stage in the clip, the two recalled for MTV News, while we were on the set, other instances of — let's call it — band bonding.

"I've got to know Justin quite well," Grint told MTV News. "Seeing just now his butt cheeks were my canvas and I was drawing stuff on his bare ass cheeks."

What Grint was referring to was the scene they were filming during our set visit, in which the Dead Boys flash oncoming vehicles as they drive during a road trip. Bartha went into a little more detail about the shenanigans.

"Today we are a shooting a scene where the Dead Boys go on the road, drive the Northeast and do a little tour," Bartha explained. "They are in certain states of disarray, trying to stay awake, screwing with each other and [my character]; he had an affinity for mooning people while he was driving."

"CBGB" opens in theaters on October 11.
