or can guess which film it's from. ONLY ONE gif per post. After that person posts their gif then the next poster/s give/s their ONE and ONLY answer for that post. NO MORE GIFS UNTIL the previous one IS solved. Then wait for confirmation as to being right or wrong. As soon as someone FINALLY gets it right he/she then posts the next gif for others to answer one-at-a-time until solved.
First-up is a REAL EASY one that the first respondent SHOULD EASILY GET...
OF COURSE, you could just CHEAT and use either Google Images or Tineye and that SHOULD give you the answer IF you're the ONLY ONE (a REAL LAMEBRAIN) on the face-of-the-Earth who DOESN'T know which film this is from.
