Walden Media issued a statement denying rumours that Kidman was involved.
“It’s a project that we’re all very excited about, but unfortunately this is just not true. Hopefully we’ll have some exciting news soon,” company spokeswoman Alison Lehrer said.
At 178cm tall, some pundits believe the pale, imposing Kidman, 36, would be perfect for the role of the White Witch, who in the book puts a spell on Narnia so that it is always winter and never Christmas.
Lehrer said filming of the multimillion dollar movie would begin this year in New Zealand and the Czech Republic.
