- Film does this too, especially when doing the "two films at once" thing. Star Wars seems to have started the trend with the ending of The Empire Strikes Back, with Han Solo being captured, frozen in carbonite and being taken to Jabba the Hutt so he could be rescued at the beginning of Return of the Jedi.
- The endings of the first two Back to the Future movies (each ending with a "To Be Continued..." at the end.) Note that the original theatrical run of Back to the Future did not have "To Be Continued..." at the end; it was only added later for VHS and TV prints when the first film became so popular, that they decided to do the sequels.
- Pirates of the Caribbean: Dead Man's Chest: Jack gets captured/killed and everyone gets ready to go rescue him.
- The Italian Job (2003) is worth mentioning - although the ending is technically of the Bolivian Army variety, it's also a Literal Cliffhanger involving an entire bus.
Charlie: Hang on lads, I've got a great idea...
- Film serials of the 1930's and 40's used this technique to bring audiences back each week to see how the heroes would get out of whatever tense situation they were last seen in. This was used to great effect in the The Adventures Of Captain Marvel serial, despite the protagonist being Nigh Invulnerable to most forms of attack. Not only did they occasionally place Captain Marvel in situations where even his invulnerability might not protect him (including one infamous death trap involving molten lava), his mortal alter ego of Billy Batson was often placed in dangerous situations, making the audience wonder if he'd be able to escape or say his magic word in time.
- The Corridors of Time, the sequel of Les Visiteurs, ended with the time-travelling knight Godefroy de Montmirail and his squire Jacquouille stranded in the middle of The French Revolution, with looming threats of torture and guillotine upon them. The sequel addressing their fate in that era finally came out... after a whopping 18 years gap.
- Planet of the Apes (2001) ended with the human in a modern world where all people are apes... to be continued. But the movie was a failure, so there was no second part.
- And let's not forget the movie The Italian Job (1969) (the original version) which ends with a literal cliffhanger that will never be resolved.
- The Last Starfighter ends with Xur fleeing in an escape pod just before the destruction of his battleship. Obviously, this was meant to be a Sequel Hook, but no sequel was ever made as of right now.
- Eragon ended with one, but a sequel was never greenlit due to the scathing reviews and low box office numbers.
- National Treasure 2 did this on an epic scale. The President's Secret Book is constantly brought up throughout the series, and is incredibly important. The cliffhanger comes in when the President asks Ben (Nicolas Cage) to "...take a look at page 47." The viewers are never shown exactly what was on it, when Ben actually looks at the page the movie cut to what the other characters were doing at the time (escaping) and it isn't mentioned again.... until the last 2 minutes of the movie, where the President asks if Ben looked at page 47, to which he replies "It's life-altering." Riley asks what was on the page, to which the presidents says, "What book?" End of movie.
- Flash Gordon: Emperor Ming has just died following being Impaled with Extreme Prejudice, right?
- So who then picks up Ming's ring with an evil laugh?...
- The Revolution, the second sequel of Les Visiteurs, ends with the two time-travelling medieval protagonists being stranded in World War II.
