"Prince of Persia" star Gemma Arterton is the front-runner to replace Megan Fox in "Transformers 3," TheWrap has learned.

An individual close to the casting process says the actress has already had discussions with Bay about the coveted role. Other possible replacements for Fox include models Bar Rafaeli, Miranda Kerr and Brooklyn Decker.

What is interesting about this is that we got a chance to talk to Gemma at the Prince of Persia: The Sands of Time premiere on Monday night. We only got her for a few seconds on the red carpet and we took that time to ask her about a possible Clash of the Titans sequel. She gave us a rather cryptic response.

"I don’t know if I am doing ‘Clash of the Titans 2.’ I haven’t seen a script yet so I don’t know if it’s happening," she said. Cool, that’s a normal reaction, but then we asked whether she would want to make the sequel, and we got this answer: "I’m not saying."

We thought it was a weird response but moved on until we read the above about the possibility of her starring in Transformers 3. We’re not sure when they would start production on a second Clash of the Titans, and one would think that she could do both, though her reaction may be telling that she’s going to concentrate on the Michael Bay sequel for now.

We’ll have to wait and see how this one turns out! We should know soon who gets the role as shooting is already getting underway.
