Bryan Singer is still at it over on Twitter, where he posted a brand new photo from the set of 'X-Men: Days of Future Past,' featuring a very '70s Wolverine and Beast.

Bryan Singer has been posting all sorts of behind-the-scenes photos from the set of 'X-Men: Days of Future Past.' So far we've gotten a peek at some of our favorite characters, including Hugh Jackman's Wolverine and Halle Berry's Storm (with fancy new hairdo). Today, Singer posted another set photo, this time of Wolverine and Nicholas Hoult's Beast with the caption, "Welcome to 1973."

There isn't much in the photo to suggest it's the '70s, aside from Hoult's suede cowboy look and horn-rimmed glasses -- though those items are arguably in fashion now, too. What is interesting to note is that Beast appears to have reverted back to his human form. In 'X-Men: First Class,' Hank/Beast created a serum to erase the mutant gene, but when he injected himself it backfired, causing him to go full-on blue, furry Beast.

'X-Men: Days of Future Past' is based on the old 1981 story line in which the characters discover an alternate future created when a brotherhood of evil mutants kills a senator, leading to a future in which all mutants are hunted by sentinels. The film stars Jennifer Lawrence, Michael Fassbender, Ellen Page, Ian McKellen, Patrick Stewart, James McAvoy, Anna Paquin, and Peter Dinklage, and hits theaters on July 18, 2014.
