Rent The Juror (1996)

Of all the men and women in the jury he chose her. He knows everything about her - what she's thinking, what she's feeling - but most of all, he knows what scares her... Demi Moore stars as Annie, a single mother determined to set her son a good example by serving as a juror in the trial of a powerful mobster. During the jury selection procedure, Annie is evaluated, not only by the judge and attorneys, but also by "The Teacher" (Alec Baldwin), a lethal onlooker. He has been hired by the Mafia to do whatever it takes to get one of the jurors to vote for an acquittal. Now, Annie is at the hands of this obsessive and maniacal hitman, and she's about to discover that justice always has a price... and this time it could be her life.
