Exposay:
Johnny Depp has gone through a variety of roles that include pirates, man with scissors for hands, and a constable in search for a headless horseman among others, but nothing scares him more than his latest role: a barber.
The 44-year-old actor says that a simple flashback scene in 'Sweeney Todd: The Demon Barber of Fleet Street' had him and director Tim Burton shaken to their cores. It was when young Sweeney's happy life before he was sent to prison by the judge.
Although seemingly normal, the actor and the director who created the movie couldn't stomach it.
"I think that was the weirdest thing I ever had to shoot," Depp says in an interview. "[Burton] literally was sobbing. He left the set of his own movie."
The 49-year-old director says the melodrama of the scene was too much to bear. "That's when I knew [Depp] was a great actor, because that was terrible. That was so bad."
