The Whip is a melodrama by Henry Hamilton and Cecil Raleigh, first performed in 1909 at the Drury Lane Theatre in London. The play's original production had intricate scenery and spectacular stage effects, including a horse race and a train crash. The production would tour overseas and inspire a 1917 film by the same name.
The Whip was a blood-and-thunder melodrama in four acts and fourteen scenes imported from London's Drury Lane Theatre. It boiled with villainy and violence. Its plot embraced a twelve-horse race on a treadmill (for the Gold Cup at Newmarket), a Hunt Breakfast embellished by fifteen dogs, an auto-smash-up, the Chamber of Horrors at Madame Tussaud's Waxworks, and a train wreck with a locomotive hissing real steam. It boasted a dissolute earl and a wicked marquis, and a heroine whose hand was sought by both knave and hero. It was a tremendous emotional dose for anyone as stage-struck and impressionable as our heroine. 
The play was adapted for the 1928 film The Whip.
