UPDATED 9/18/2015 10:55 AM PT: Marc Guggenheim has clarified to CBR that his tweet was not Metal Men related, but rather an Easter Egg reference to "Newstime," a magazine that exists within the DC Universe of the comic books, where Clark Kent once worked after leaving the Daily Planet.
Original story: Executive Producer Marc Guggenheim dropped a "DC's Legends of Tomorrow" hint via Twitter on Friday -- and well, a fake magazine cover focused on platinum mining has got everybody thinking this is likely Metal Men-related.

DC Comics' Metal Men date back to the Silver Age, introduced in 1962 by creators Robert Kanigher and Ross Andru. They're commonly depicted as advanced robots created by Will Magnus; named Gold, Iron, Lead, Mercury, Tin and, yes, Platinum. The Metal Men would seem to be a natural fit for the sci-fi-flavored "Legends of Tomorrow," which already includes Brandon Routh as The Atom (equipped with a scientifically advanced, shrinking super-suit) and Arthur Darvill as Rip Hunter.
Of course, it's just a tease at this point, though with the show now in production, a steady flow of new information is likely. "DC's Legends of Tomorrow" is slated to debut midseason on The CW.
