Writer/director Rian Johnson has given this first look at the time machine in his upcoming sci-fi pic Looper on the film’s Tumblr account, where you’ll find more behind-the-scenes photos.

In the September 28 release, Joseph Gordon-Levitt plays a contract killer who works for the mob of the future, and who kills victims that are then sent back in time 30 years so there’s no trace of the crime. One day, however, he recognizes one of his targets (Bruce Willis) as a future version of himself.

Emily Blunt, Paul Dano, Xu Qing, Noah Segan, Jeff Daniels and Piper Perabo co-star.
