Johnny Depp and Helena Bonham Carter in 'Sweeney Todd: The Demon Barber of Fleet Street'

Director Tim Burton insisted on a bloody mess as his ghoulish barber slashed clients in gory scenes.

Depp says, "I remember everyone except me being covered in plastic trash bags. There'd be a countdown: 'Three, two, one... action!' And then blammo... the great deluge.

"It tasted kind of like a Karo-syrupy sort of thing. It was oily and it was dangerous, slippery.

"You'd see these big English grips, tiptoeing through the swamp of blood."
