Though John Barrymore is top-billed in Bulldog Drummond's Peril, the aging matinee idol is consigned to the supporting role of Inspector Nielsen. Drummond is portrayed by John Howard; once more, he is on the verge of marrying the ever-patient Phyllis Clavering (Louise Campbell). And yet again, the ceremony is interrupted by a late-breaking crime. The villains this time are trying to steal synthetic diamonds. Bulldog Drummond's Peril was the 5th in Paramount's B-picture "Drummond" series. ~ Hal Erickson, Rovi
