Sandra Bullock and Melissa McCarthy star as two mismatched cops in this comedy from 'Bridesmaids' director Paul Feig. Unaware that her colleagues hate her, prim and priggish FBI special agent Sarah Ashburn (Bullock) is seconded to Boston where she's forced to team up with foul-mouthed, take-no-prisoners detective Shannon Mullins (McCarthy). When the pair are ordered to take down a local drug baron, the two cops' wildly contrasting styles - and mutual hatred - soon threaten to derail their mission. But as the weeks pass, a grudging admiration for each others' methods brings about a thawing in hostilities, as the ill-starred crimefighters turn out to be a force to be reckoned with.

Teenager Marty McFly (Michael J. Fox) just wants to play electric guitar and date girlfriend Jennifer; he is also determined not to end up a loser in life like his own parents. Father George (Crispin Glover) is a weak-willed failure, bullied at work by his former high school tormentor Biff Tannen (Thomas F. Wilson), while mother Lorraine (Lea Thompson) is an alcoholic. Marty's friend and mentor is the eccentric Doctor Emmet Brown (Christopher Lloyd), who has successfully invented his own time machine in the form of a plutonium-powered Delorean sports car. However, after Marty travels thirty years back in time, he discovers that he doesn't have enough fuel to return to 1985. And, after he accidentally prevents the first ever meeting between his own, teenage parents, Marty's own future birth and present existence is placed in jeopardy!
