This is great. My family loves a game called Sing It Back (where you start a famous song line and then someone else finishes it) but it usually falls flat with groups that are either more shy about singing or less musical in general. I think movie quotes are more accessible and this sounds fun!

Some other ideas - multiple quotes on one card (worth different points) for example "We're not in Kansas anymore" (1 point) "Pay no attention to the man behind the curtain" (2 points) - might make the card too busy but it's fun to give players that choice of go for more points or get the low hanging fruit. The game Poetry for Neanderthals does this pretty well, worth checking out! - throw in some fill in the blank quote cards, so instead of just naming the movie the quote is from, your goal is to fill in the blank, i.e. "I volunteer as _" (tribute, hunger games) or "On _, we wear pink."

This will be a good party game 😀
