Although Superman hasn't returned ... yet, director Bryan Singer has been hard at work on a film that's temporarily removed him from the comic book world and placed him right smack in the middle of World War II. The Daily Mail has published the first photo featuring the seven men who plotted out a mission to assassinate Adolf Hitler on July 20, 1944. In front of the men -- and printed off Google Maps -- is their ill-fated plan. Is it just me, or do these guys look like they mean business? Pictured from left are actors Kevin McNally, Christian Berkel, Bill Nighy, Tom Cruise, Terrence Stamp, David Schofield and Kenneth Branagh.

Apart from the photo, The Daily Mail also provides a brief bio for each of the men. Unfortunately for each of the seven, since this was such a dangerous plot, if they were to fail it would most likely cost them their lives. And, as we all should know -- spoiler alert -- they were not able to kill Hitler. Thus, reading the ways in which each man perished was rather, um, depressing. With a screenplay from Nathan Alexander and Christopher McQuarrie (The Usual Suspects), Valkyrie is set to arrive in theaters on June 27, 2008.
