Kurt Wimmer (Salt, Total Recall) has officially signed on with Sony Pictures to write the blockbuster action sequel, Salt 2. The original, directed by Philip Noyce and headlined by Angelina Jolie, grossed $293 million at the worldwide box office, so naturally the studio is eager to get a sequel in gear as soon as possible. And as Deadline pointed out, Jolie is apparently very happy to do a sequel so long as it's handled correctly.
