Homicidal zoologist Eric Gorman would have a tougher time disposing of his wife’s lovers in modern-day Washington than he did in Edward Sutherland’s 1933 thriller, Murders in the Zoo. Locked inside a cage at the National Zoo, the doctor’s victims would be much more likely to trip over a rat corpse and get knocked dead than to actually perish in the jaws of a healthy zoo resident. Though limited to a supporting role in Murders, actor Randolph Scott would go on to become a leading man in dozens of big-budget westerns, turning into one of the top box-office attractions of the early ’50s. Murders screens with Colt .45—in which Scott stars as a gun salesman forced to clear his name when his sample case is stolen by a gang of outlaws and used on a deadly robbing spree—as part of a double feature that starts at 7 p.m. at the Capitol Hill Arts Workshop, 545 7th St. SE. $5. (202) 547-6839. (Matthew Borlik)
