I'm getting javascript errors when I click 'Go', it says there's a 404 on /randomMovie/undefined.

I like the idea though, and look forward to it working. You couldn't add links to IMDB and Letterboxd could you? Would be great to add films to my Letterboxd watchlist or look up the cast and film info on IMDB.

I'll look into it, I'm getting the same error while the page loads as well however it should work after it's loaded, and you select genres and then click 'Go'.

I probably will add functionality for IMDB/Letterboxd and other services, this was just a quick put-together :)
