“Twilight: Breaking Dawn” Cast On Lockdown In Brazil

Blame it on Rio!

Sex scenes and birth scenes are okay, but there will be no unplanned pregnancies, drug-fuelled romps, or one-night stands during the filming of The Twilight Saga’s two-part finale, Breaking Dawn.

Are we crystal?

Twilight producers at Summit Entertainment are reportedly pooping the party on the Brazilian set of the film, where the law has been laid down to the stars of the mega-successful movie franchise, British tabloid Now dished last week. The Twilight team has been being to told they’re in town for work, not play – they’re banned from partying, smoking, and sneaking in and out of each other’s hotel rooms. (Here’s looking at you, Rob and Kristen.) The cast — which includes Young Hollywood aficionados Taylor Lautner, Kellan Lutz, and Ashley Greene — is reportedly rather irked, particularly since they’ve all been on good behavior since the series began filming a couple of years ago.

“It’s like high school and the producers are the principals,” someone in production yapped to the tab. “Everyone does their job well. That’s why it’s so successful. It’s like they’re being victimized for being young. That’s not fair.”

We’ll see whether or not Summit’s hardnosed set practices paid off when The Twilight Sage: Breaking Dawn hits theaters on Nov. 18, 2011.
