According to The Hollywood Reporter, Sony's Casino Royale kicked off its long-anticipated production in Prague on Friday. Although the globe-spanning shoot has locked down exotic locales and an intrigue-laden script, at least two things are still missing: a leading lady and a worthy opponent for Agent 007.

Although it isn't unprecedented for a studio to begin principal photography on a film with two major cast elements unsettled, it is unusual for a project of this budget and scope. However, a source familiar with the Martin Campbell-helmed production said scenes involving James Bond's love interest don't begin for more than a month, and the studio still has some breathing room before compromising the film's schedule.

"They're talking to three to four girls right now", Royale scribe Paul Haggis said. "Every week I read there's a new Bond girl, and I call them and they say, No, you idiot."
