Daniel Radcliffe, Jack Black and Conan O’Brien have been spotted filming their upcoming Weird Al biopic in Los Angeles. The actors got into character in wigs and garish costumes as they transformed themselves for the movie based on the American comedy musician. Radcliffe was far from incognito as he donned a big curly wig, a Hawaiian print shirt, a moustache and round wire-frame eyeglasses for the title role.
