Pity the double life of the modern-day movie star. While she spends most of her working hours stepping into the less-than-glamorous roles of say, a miner, a hit woman or a flight attendant, come time for premieres and personal appearances, she must metamorphose into a picture-perfect starlet. Out on the town this week, these ladies have managed to do just that with designer frocks, upswept hair, jewels and their very own megawatt smiles. And nary a coal smudge or bullet in sight. Guess that’s why they call them actresses.
