Cinema, like literature, is full of phrases that mark us or impress us, although some of them we no longer remember or have a common use. This is the case of the ones I can remember now:
"Touch it again, Sam", that although it wasn't said exactly like that by Ilsa or Rick in Casablanca, it has remained in us; "Will you stop, Dave? Stop it, Dave. I'm scared. (...) Dave. My mind goes away", from what the computer HAL 2000 tells Dave when he's disconnecting it, in 2001: space odyssey; "Judging is what defeats us", one of Colonel Kurtz's harsh phrases in Apocalypse Now. Thank you for your gratifying post, @ladyrebecca.
