The best thing that can be said about Abbott and Costello Meet the Keystone Kops is that it's better than the team's previous outing Abbott and Costello Meet Dr. Jekyll and Mr. Hyde. Set in 1912, the film casts Bud Abbott and Lou Costello as a couple of New Yorkers who are swindled out of their life savings by a crooked lout (Fred Clark). Pursuing the villain to Hollywood, the boys discover that the double-dealer is now posing as an autocratic Russian film director. To put A&C out of the way, the crook and his partner in crime (Lynn Bari) hire the boys as stunt men, intending to kill them off at the first opportunity. But the comic duo save the day when they enlist the aid of the Keystone Kops in capturing the fleeing villain, who has absconded with the studio payroll. Pretty dull stuff for most of its 78 minutes, Abbott and Costello Meet the Keystone Kops finally comes to life during the climactic chase, which is every bit as funny and thrilling as anything put together in the silent era. Though the film is rife with anachronisms, a measure of authenticity is achieved by such silent-era guest stars as Mack Sennett (who gets to throw a pie at Costello), Heinie Conklin, Herold Goodwyn and Hank Mann.
