Nicolas Cage was a "mischievous kid" on the set of 'The Sorcerer's Apprentice'.
The Hollywood legend confesses playing the role of the titular sorcerer in the movie made him act in a childish way with his co-star Jay Baruchel as it made it more fun while on set.
He said: "I would say to Jay, 'Are we in trouble yet?'
"It has to be like that. You have to have a bit of mischevious kid in the back of the classroom to make it interesting.
"I have to make it amusing for me, which means there has to be some level of mischief and public disruption."
The 46-year-old star also admits he came up with the idea of a ring holding all of his power, as the producer and director had different suggestions.
He told MTV News: "I was in Hungary making another movie and I got a call from producer Jerry Bruckheimer and director Jon Turteltaub and they said, 'We want you to maybe wear bracelets and hit these bracelets and that's when the magic happens,
"Interesting, but I said, 'No, it has to be a ring because I have to use my hands.' It's like conducting. I really wanted to be able to conduct the magic into happening. ... It's more beautiful to use your hands than just smashing your wrists together."
'The Sorcerer's Apprentice' hits cinemas internationally throughout July and August.
