I'm a big fan of Carlo Ledesma's The Tunnel.
I won't say too much about this little Australian gem for fear of spoiling it...but, I will say that you need to turn off all the lights in your home right now...put on some decent headphones (the sound design is really impressive)...and hold on tight. It is a tension-filled horror film full of build-up that will ultimately rattle your bones.
Click play...and enjoy...The Tunnel...
Thanks for watching!
