Movie puzzle

Jon Delfin posted this link on the Cruciverb mailing list—it's a British office-supply company's contest that's not open to American entrants, but you can still play along and try to decipher the 20 movies depicted by tableaux of office supplies. My husband and I figured out 17 of them, but we're stuck on #8 (five staple removers), #9 (highlighters and markers facing off in a road), and #14 (paperclip person run over by truck wheels of tape). Anyone have any subtle hints about those three? Or are there others you're stuck on?
