I think you should watch all you tube videos of WARREN BUFFET, the greatest investor of all time.
He now is the fourth richest man in the world. And only by buying some good stocks/business he has made that much fortune.
So please also read all books written describing his investing style.
money never sleeps, very nice movie
Some of them that I have liked other than what is already mentioned:
Margin Call
Rogue Trader
Boiler Room
Pursuit of Happiness
The first ever movie that I watched related to markets - 'Trading Places' . Very well made, highlights the role of skill and luck in a trading as a career. Besides the movie stars Eddie Murphy who can tickle your bones :)
Of course 'Rouge Trader' is awesome. Gives a sense of what may happen if you don't own up to your mistakes in markets.
Gafla - Bollywood movie, loosely based on Harshad Mehta. Quite well made.
Money never sleeps
Wall Street
Wolf Of Wall Street
The ones that I have watched and liked is :-
Wall Street & Wall Street 2 (Money Never Sleeps)
Wolf of Wall Street
Jurassic Park . . .
Titanic . . .
Evil Dead . . .
Friday The 13th . . .
My personal favorite is ‘Wall street’

The Pursuit of Happyness
I, too, like this movie.
