The lead actors haven't been confirmed and we've no idea what the plot will be but each instalment of the new Star Wars' trilogy is likely to cost between $175-200m (€126-145m).

Disney chairman Alan Horn quoted the figure in an interview with Bloomberg TV. This would make the new Star Wars films, which are being directed by JJ Abrams, the most expensive in the space opera series. 

"We actually don't even have the completed budget yet but it will be in that range," said Horn. "These large, tent-pole kinds of movies, on the expensive side, are in the neighbourhood of $175-200m  (£126-145m), that kind of a number - some are more, some are less."

"We need to give the audience, essentially, a full meal in return for their affection and devotion and love for these properties," he added. "We don't give budgets out. But it will be a big, tent-pole movie budget."

The last Star Wars films, prequels The Phantom Menace, Attack of the Clones and Revenge of the Sith, cost around $115m each a decade ago. The original 1977 Star Wars cost just $11m, around $43m in today's money.
