Fan Casting Working Girl (2008)

Unhappy with her job and her loser boyfriend, Tess McGill takes a secretarial post at a major Wall Street firm. Her boss is Katherine Parker, an outwardly affable yuppie whose grinning visage hides a wicked and larcenous propensity for exploiting the ideas of her employees. While Parker is incapacitated, McGill is compelled by circumstances to pose as her boss. Her inborn business acumen and common sense enable McGill to rise to the top of New York's financial circles, and along the way she wins the love of an executive, Jack Trainer.
