Here’s a good warm up act for the big budget Tom Hanks film, “Captain Phillips,” about the hijacking and rescue of the crew of the Maersk Alabama. “A Hijacking” promises to be a more straightforward account of a hijacking — one without Seal Team 6 saving the day. A Danish ship is taken, and we see the drama play out on board and in the boardroom, where the owners negotiate. “A Hijacking” opens in late June.
