In February director Roman Polanski announced his plans to direct a mega-budget disaster movie about the eruption of Mt. Vesuvius in 79 A.D. and its destruction of the nearby Pompeii.

Now, the first casting rumors have emerged over at Omelete.Br who report that Orlando Bloom and Scarlett Johansson has been in early talks about taking lead roles in the $130 million production.

Bloom would play Marcus Attilius Primus, a young engineer sent to repair the greatest aqueduct in the Roman Empire, which brings water to 250,000 people on the Bay of Naples. Taking on the corrupt political forces to get the job done, he soon finds himself facing an even greater threat - Mother Nature herself.

A five month shoot is scheduled to get underway in August.
