Christopher Nolan's upcoming film Interstellar looks incredible. A new special effects-heavy trailer was aired exclusively at Comic-Con last week, and now you can watch it too so long as you have this secret code.
The trailer sits behind a special passcode-wall on the Interstellar website. The passcode is 7201969.
That code is extra special, because when viewed in the US date format of MM/DD/YYYY, you find it's the date man first landed on the moon. 20 July, 1969.
The trailer goes pretty quick, so be sure to check out the amazing stills in our breakdown post.
