Pierce Brosnan has revealed writers are hard at work on The Thomas Crown Affair 2.

The 56-year-old - who co-starred with Rene Russo in 1999's The Thomas Crown Affair, which was a remake of the 1968 film - has long been rumoured to be starring in a sequel, possibly directed by Paul Verhoeven and co-starring Angelina Jolie.

Pierce told ComingSoon.net: "We've got the fourth script in and this is the closest we've gotten in structure to making sense. It's very very hard. Now we have the character, it's not really fleshed out, so we have to work on him, Mr Crown, and her, Miss Moore, another affair, more art, but it has to be an unexpected surprise."

The former James Bond is currently appearing in Roman Polanski's The Ghost Writer and Chris Columbus' fantasy-adventure epic Percy Jackson And The Lightning Thief.

But while a Thomas Crown Affair sequel looks likely, Pierce doesn't think Mamma Mia! 2 is in the pipeline.

"I don't think it's going to happen. I think we did it, it's done and dusted," he said.
