Pretty Things (2001)

Lucie, a successful and assertive fashion model, embodies a commanding "Type A" personality, while her identical twin, Marie, is the complete opposite—shy, quiet, and unassuming. When Lucie lands a highly sought-after recording contract in France, she faces a major hurdle: she can't sing. Meanwhile, Marie, who has a beautiful voice, impulsively heads to Paris to impersonate her sister without telling anyone. Unbeknownst to her, this decision sets off a chain of perilous and violent events that neither sister could have anticipated.
