Salt (out Aug 19) is a fast-paced action film starring Angelina Jolie has a CIA agent on the run from her colleagues after being named as a possible Russian spy.  Can she prove her innocence?  This has been well directed by Aussie Phillip Noyce (I like the short running time) but I had trouble with (1) the motives of certain characters and (2) how Angelina could beat up so many people. To each their own. Grade: B-.
