Atwitter for Cannons

Former “Superman’’ Brandon Routh, who just finished filming the lacrosse movie “Crooked Arrows’’ around Massachusetts, tweeted his congrats to the Boston Cannons, who won their first Major League Lacrosse Championship over the weekend. Routh tweeted, “Cheering for my (current) home team - @BostonCannons’’ during the game and then celebrated the win with this note: “(MLL Spoiler) Congratulations to the @BostonCannons on their 1st @MLL_Lacrosse Championship!’’ In “Crooked Arrows,’’ Routh plays the coach of a Native American lacrosse team that takes on a prep school. The movie has pretty much wrapped, but the crew is still in town. Boston Casting sent out a last-minute call yesterday for a scene being shot throughout the day in Topsfield.
