More style than substance -- but fun, if gun-heavy, action.
Parents need to know that this movie based on the graphic novel by Dave Stevens can get pretty violent. There are plenty of car chases, aviation disasters, gun fights, and explosions. A mobster holds a character's head close to a restaurant grill, but doesn't cause injury. The bad guys are killed off mainly by gunfire, with the exception of the two nastiest characters who are burned to death. There's some mild language (mostly "damn" and "hell") and sexual content too as a drugged heroine is revived and (unsuccessfully) seduced in the villain's bedroom. Kids will get a bit of a history lesson with the movie's depictions of Howard Hughes and W. C. Fields and a classic newsreel shown in a theater.
