Hollywood is apparently working on a G.I. Joe movie focusing not on Duke, Scarlett, Roadblock, et al., but rather, on Chuckles. Which might raise some eyebrows if all you know are the cartoons. But Chuckles is the main character in one of the best G.I. Joe comic storylines, “The Last Laugh,” in which he goes deep undercover to infiltrate a radical new branch of Cobra. It’s gritty and hard-hitting, but in a good way, and it could make for very good spy thriller once you get past any nostalgia associated with the “G.I. Joe” label.
