Burning the midnight oil, Amy Adams and Christian Bale showed up on the set of the new Untitled David O. Russell project in Boston, Massachusetts last night (March 26).

The “Julie and Julia” hottie looked retro-chic as she filmed scenes with her “Dark Knight Rises” costar, both dressed in vintage clothing for the 1970s-set flick.

Though we all assumed he hung up his cape after the Christopher Nolan trilogy ended, Christian Bale may return as Batman in an upcoming film based on the Justice League.

A DC Comic creation, the Justice League consists of the caped crusader along with original members Superman, Wonder Woman, Flash, Green Lantern, Aquaman, and the Martian Manhunter.

While things are tough for leukemia patient Zach Guillot these days, his recent conversation with Christian Bale definitely brightened up his day.

The “Dark Knight Rises” hunk phoned the 8-year-old boy, who boasted that he had a cardboard Batmobile and authentic Batman suit.
