if by the title you mean: films you will ALWAYS watch all the way through if they come on the telly.

Then I've got a few

John carpenter films:
The Thing
Escape from new york
Vampires

Bruce willis - Hudson Hawk, I know the critics hated it. I don't know why I love it !

Evolution - just one of the best films ever made, never really really went mad for the x-files or any other duchovny tv series. But Evolution is the best wrok he'll ever do.
Just an awesome film !

Shrek - the first film, the others are okay but the first is the classic.

Cabaret - my all time favourite musical.

Wings of desire, wim wenders film - and peter falks finest on screen performance. Without him the film would just be another arthouse film. With him it's a total classic.

Enter the dragon - 'boards don't hit back'. A martial arts classic for all the right reasons.

District 13 - probably the best action film ever made. Stars the guy who invented parkour - David Belle - and one of his best pupils. Both also world class martial artists.
Some of the stunts need to be seen four or 20 times for you to believe they are even possible, let alone done with such ease and NO digital effects or wires.
If you've never seen it - go find it and prepare to disbelieve your own eyes ! 

Guardians of the galaxy - the best marvel hero film, bar none.

Brotherhood of the wolf: has a naked monica belucci in her awesome prime - I could stop there And also a cracking martial arts film as well.

probably  others, I will update the list as I think of them.

Where films are in a foreign language to me ie: (not english) I only watch the originals. Just can't stand dubbed films and if you can't read subtitles and watch a film at the same time - you're probably dyslexic and you have my sympathy.   

A few of my favourites are:
Kung fu Hustle
Oldboy (2003 version obviously)
Apocalypto
City of God
Big Lebowski
Lord of the Rings trilogy
The Matrix
One Flew over the Cuckoos Nest
2001 Space Odyssey
Trainspotting
