Jamaica Plain actress Julia Jones, who appears in the indie movie “Missed Connections” with Sting’s daughter Mickey Sumner, had a busy week in New York. She was spotted at Fashion Week with her boyfriend, Josh Radnor of “How I Met Your Mother” fame, and then brought Sumner to the NYC premiere of Radnor’s new movie, “Liberal Arts.” Radnor directs and stars in the film, which also features Jones’s “Twilight Saga” costar Elisabeth Reaser. Jones returns to the big screen as Taylor Lautner’s werewolf sidekick in “The Twilight Saga: Breaking Dawn — Part 2” in November.
