Re: I made a website that shows you a random classic movie, and I need some advice for a better layout.

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.

When change the movie use Javascript to change the css of the controls.

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.
