Partial answer:

I did a little rearranging by seat number, and the first letters of the movies spell out THE TIMES WILL POINT TO IT.

Partial answer:

Plotting the clocks on a seating plan map puts them in a trail but I can't make out any more than that yet: http://jsfiddle.net/7tdhvysu/5/


EDIT 1: The first one is on row 3 and points to the 1, the second is on row 4 and also points to the 1, and the next one down points to the 5. These are the starting numbers for pi: 3.1415..., which points to The Life of Pi


EDIT 2: Reversing the order of the rows doesn't help: http://jsfiddle.net/8rbd5pv9/


EDIT 3: There are a number of them with the same minutes right next to each other, in fact there are 6 "pairs" of same minute hands next to each other - perhaps relevant? One of those pairs contains "12" minutes, which is abnormal to the others which are all multiples of 5.


EDIT 4: Based upon the two hints, it would appear that the film title relates to a number. Clockwork Orange also screams out at this point so I wonder if somehow the numbers of the times are able to be formed to produce the hex code for Orange?

I tried too rearrange then draw the clocks:

Potential partial answer building on generalcrispy's partial answer:

I tried drawing the times for an analog clock and noticed that the hour arms usually point more or less directly at another clock (Except those that point out of the image), but i have not been able to establish any kind of pattern, but thought this might save others some time or give them ideas. Maybe they need to be rearranged?

The minute arms doesn't seem to point at anything in this configuration

I think it is

Ocean's eleven? Because it starts around 9:55 pm and you are invited for movie night.

Building off @generalcrispy's answer (you were SO close if I'm right):

"THE TIMES WILL POINT TO IT." (Emphasis added)

So the movie you'll be watching is:

IT (Scary!)

You're going to watch:

Titanic

Because

Graph the seats, they form a continuous line of an object. Rotate that object (i.e. assume the first and last points are at the same level) and it's an iceberg.

I think it is

La La Land

because

The seat and row numbers add to 15, the exact start time of the movie. None of the other tickets' seat/row numbers add up in this way.

You are going to watch the classic:

Hot Shots

because

there are 2 sets of times that are duplicates:
12:05 and 12:30

these are:

The Third Man,
Harold and Maude,
Over the hedge,
Shutter Island,

Which is formed by

Taking the 1st letter of each movie (SHOT) and using each letter twice, getting HOTSHOTS

I have tried my best to evaluate each ticket on similarity basis bcos two ticket are required to watch the movie.But no similarity is found as far as row & seat no is concerned. Only similarity is found in timing of movies. So on the similarity of timing I can conclude that they will go one of
following movies
1 Edward Scissors Hands timing 18.25
2 Toy Story 2 timing 18.25
Moreover there seats are in line one behind other.

Judging by the answers and hints provided thus far, I suspect the plot of the film heavily involves Time Travel

Since some movie times happen concurrently, I imagine there are different versions of characters experiencing events from different viewpoints.

The best movie example for something like this is

Predestination

Which may fit the bill as one of the hints mention that the movie title is not on one of the tickets.

I thought you were going to watch

A Streetcar Named Desire

but I can't quite make that fit.

Of course, you might just be heading out to watch:

Enigma (by which of course I mean The Imitation Game)
