Here now is another entry with movie lines from well-known films which I don't hear quoted as often as I think they should be.
1. The Bride of Frankenstein (1935):
"He bears a strong resemblance to me, don't you think? Or do I flatter myself?"
I must also point out how the character does not freak out when he finally encounters the Monster (Boris Karloff). Naturally, we know that it is due to his plans to create a mate for him, but the fact that, due perhaps to his own unusual persona, Pretorius instantly treats the Monster with more respect than other people makes his demise at the film's end somewhat sad.
2. Goldfinger (1964):
The most famous line is Goldfinger (Gert Frobe) telling Bond (Sean Connery) he expects him to die as 007 is pinned down by an approaching laser beam and asks Goldfinger if he expects him to talk.
But Bond talks him out of killing him and is eventually taken to Goldfinger's horse ranch in Kentucky. Upon arriving, Goldfinger greets him and refers to a passing horse asking Bond:
"Lovely animal, isn't she?"
To which Bond replies:
"Certainly better bred than the owner."
Needless to say, Sir Sean's ability to deliver nice lines with such aplomb was something both Daniel Craig's and Timothy Dalton's Bonds could have really used.
3. Star Wars (1977):
The Princess Bride, this movie has many lines which had been ingrained into pop culture. So, like the aforementioned Rob Reiner film, maybe it was inevitable that one line got lost in the shuffle.
For me, that line comes after our heroes escape the Death Star and fight off some TIE Fighters. Han Solo (Harrison Ford) then tells Princess Leia (Carrie Fisher):
"Not a bad bit of rescuing, huh? You know, sometimes I amaze even myself."
The Princess replies with:
"That doesn't sound too hard."
I'd say that many subsequent movie romances end up falling flat on their face because nice, unforced dialogue such as this has become more the exception than the norm.
4. Halloween II (1981): review of the film, it does deserve some credit for its nice camerawork and, perhaps even more importantly, reuniting almost all of the same people who worked on the first film (on both sides of the camera).
While the film should be faulted for both its Star Wars-esque revelation of the relationship between Michael Myers and Laurie Strode (Jamie Lee Curtis) and for giving us the darkest and most understaffed hospital in movie history, it is still entertaining thanks mainly to Donald Pleasance who, in the midst of this nonsense, gives us a wonderful reprisal of Dr. Sam Loomis, who relentlessly hunts Michael down in order to stop his reign of terror.
The film begins where its predecessor ends when Loomis saves Laurie's life by shooting Michael off the balcony of the two-story house where she was babysitting. When Loomis realizes Michael's body is gone, he goes outside to investigate. A neighbor then comes out asking what the commotion is about. When Loomis tells him to call the police, the neighbor says he's been trick-or-treated to death already. To which Loomis replies:
"You don't know what death is!"
It's a pity a stronger film wasn't built around this great line.
5. Total Recall (1990):
While Arnold's line "Consider that a divorce" became famous, there is a line from the villainous Vilos Cohaagen (Ronny Cox) when he confronts Quaid (Schwarzenegger) at the film's climax which I found hilarious.
"In 30 seconds, you'll be dead, and I'll blow this place up and be home in time for corn flakes!"
Maybe it's the way Cox delivers the line, but I just didn't expect the guy who played Dick Jones in Robocop (1987) to say a line that would crack me up.
