Warner Bros bosses are reportedly fearful the extras will take on-set pictures of the cast, including Eddie Redmayne and Colin Farrell, but the decision to confiscate their phones has become a source of controversy, with the extras saying they need to have access to them in order to accept future work.

One unnamed extra told The Sun newspaper: "We're being treated like children. The production team is paranoid and many of us are thinking of telling them where to shove their job."

Agency Casting Collective has raised the issue with Warner Bros.

Meanwhile, 'Harry Potter' star Daniel Radcliffe admitted recently he will be "first in the queue" to see the much-discussed prequel.

The 26-year-old star said he is pleased he isn't going to be a part of the new project and is simply looking forward to enjoying it as a fan.

He said: "I'm really happy they're doing it, but I like that I'm not involved.

"I know very little about it, but I'll be first in the queue."
