"Flirting With Danger" is a very strange old film. It stars Robert Armstrong (of "King Kong" fame), William Cagney* (Jimmy's brother) and Edgar Kennedy as three guys who love working with explosives and chasing women. Of the three, Kennedy seems obsessed with explosives and fireworks and nearly blows himself up several times during the course of the movies. He's also the least interested in women. This makes for a very odd film--one with a lot of comedy, a bit of romance and a lot of bizarreness! Overall, it's a highly uneven and strange film. And, oddly, there really isn't much in the way of plot. However, it is enjoyable--even with all of its many deficiencies as well as the inclusion of an annoying stuttering character (uggh!).
While William made a few films, he never caught on as an actor. Later, he became his brother's agent and produced quite a few of his films.
