Perhaps Mascot Pictures' The Marines are Coming would have been more credible had it been made 10 years earlier. Stars William Haines, Esther Ralston and Conrad Nagel are game, but all three are a bit long in tooth for their characters. In a throwback to his silent films, Haines plays a wise-guy marine, while Nagel is his more-serious best friend. Both men vie for the attentions of cute blonde Ralston, but South-of-the-Border tootsie Armida complicates matters. Everything is resolved after an exciting battle between the U.S. Marines and a gang of Mexican bandits. William Haines retired from films after The Marines are Coming, going on to a highly successful career as a Hollywood interior decorator.
