Zac Efron's drug role

Zac Efron's character will take drugs in the 'Hairspray' sequel.

Composer/ Producer Marc Shaiman - who worked on the 2007 remake - has revealed details of the plot for 'Hairspray 2', saying scriptwriter John Waters, who wrote the original 1988 movie, has come on board to pen the next instalment, which sees Zac's character Link Larkin experiment with narcotics.

Marc said: "John Waters wrote a treatment that is so f***ing hysterical!

"People hate Tracy, played by Nikki Blonsky, because she doesn't lose weight. They ask 'Now that you're famous, why won't you lose weight?'

"And Link experiments with drugs. Throughout half the movie, he has an ongoing dialogue with three pimples on his forehead. He gets caught up trying to masquerade himself as a member of the British Invasion. And it's wearing that mop-top Beatles hairdo that causes those pimples on his forehead!

Despite John Travolta ruling himself out of reprising his cross-dressing role as Edna Turnblad, the character will still feature in the sequel.

Marc added: "Edna loses weight, but sees her husband lusting after fat women.

"And so, she finally breaks down and runs over to a snack table. Just within one number, she gets fat again; gaining 20 pounds at a time. Her fat pops out, and by the end of the song she's completely at her old weight again."'Hairspray 2' is set for release in 2010.
