Looks already quite good to me. But since you probably want people to focus on the content ( = video ), why not tone down the background-opacity a bit, except for the header. ( And have the cool tiling background pattern also there (: really should have a header element though ). Have some air between the video and the filtering (on larger screens).
You could change the controls color to match the film, as you make the background change, I do believe that you have a database with the description, movie URL, background image and the other data (year, genre, etc), you will need add a field for a color value (hex, rgb, rgba you decide), and with the insertion of the movie data insert the color.
Other things that would be nicer too are:
A wide player, beside fullscreen, some like youtube uses, where you can have a small, medium and fullscreen, so on medium the player would fill the top and the controls will be placed below.
A mobile version, with the background, video, controls and description. (Media queries can help).
These are just suggestions as you asked, you not need to do them, but could at least give a look, try, and if fits improve on the actual design.
I like the layout – it’s simple and straight-forward. I agree with ooredroxoo, however, on a few points: namely, the player could use more width to grab more attention and the background could be more opaque like Atelierbram noted, as some of the text was difficult to read on some of the background images.
Neat concept and overall great actualisation of it.
