There are so many and so many different accents that it depends on your preference. I would probably stick to movies about "normal" life and not rated R, since they will use more everyday and "polite" conversation (meaning less bad words). Some suggestions with mixed accents: Letters to Juliet (she's American he's British), Serendipity (He's American, she's British) The Holiday (Has a British and an American man/woman) The Parent Trap (with Lindsay Lohan when she was young and still innocent), Leap Year (she's American he's Irish) How to Lose a Guy in 10 Days (His accent is southern American) Others perhaps: Crazy Stupid Love The Proposal Elizabethtown ("Clair's" accent is not standard American) Tangled (yes, a Disney princess movie, but it is mostly modern American language) What Happens in Vegas New Years Eve

You can only improve your listening comprehension by watching a movie, but you cannot improve spoken language until you speak with people.
