Actress Amy Adams was spotted in Boston on Monday as she made her way to the set of the David O. Russell film that’s been shooting in the area. No word on how the weather would affect production of the film, which takes place in the ’70s and costars Bradley Cooper and Jeremy Renner. . . . On Sunday, the Globe ran into Radioman (sometimes known as Craig Castaldo) the former New York City homeless man who went on to have dozens of cameos in television shows and movies. A documentary was made about him last year that featured commentary by actors such as Josh Brolin, George Clooney, and Matt Damon. Radioman told us he was in the South End to get an autograph from actress Charlize Theron, who was in the neighborhood to produce the locally shot pilot for the new “Hatfields & McCoys” series.
