Now you listen here to me, boy. And you listen good. I'm gonna count to three, and when I do, you're gonna tell me where my treasure is. Cause if you don't, I'm gonna blow your head off.
~ Merrick telling Haakon to give him his treasure.
John Merrick is the main antagonist of Disney's 1990 Norwegian film Haakon Haakonson (released in America as Shipwrecked). He is a pirate captain who poses as a member of the English military and eventually takes over Haakon's ship after the original captain, Madsen, mysteriously dies and proceeds to make life difficult for everyone.
He was portrayed by Irish actor, Gabriel Byrne.
Merrick has eluded the British Navy and returned home to London. He promptly kills an officer named Howell to obtain his first officer's papers.
In London, Madsen and Bosun take on Merrick, masquerading as Howell, who's familiar with the South Seas and the ways of pirates. Later, Merrick's cohort taints Madsen's cognac; he falls ill with fever and dies. Merrick is then captain. Arriving in Sydney, Merrick cancels shore leave and takes aboard a scurvy gaggle of men.
Work onboard ship soon becomes terrible for Haakon, Jens, and the original sailors, which intensifies when the new captain finds Mary (the stowaway girl trying to reach her uncle in Calcutta) and demands whomever has been fraternizing with her to show his face. Haakon admits responsibility, and the captain sentences him to be lashed with the cat o'nine tails. Jens protests, saying that whipping Haakon would be an effective death penalty, to which Merrick orders that Jens will be punished instead. However, before anyone can be flogged, the court martial is interrupted by a terrible storm that damages the mainmast, then sinks the ship. Haakon takes advantage of this to escape the doomed ship and wakes up on a deserted trpoical island.
After searching the island, Haakon discovers treasure as well as a wanted poster for an Merrick. Haakon discovers that the new batch of abusive shipmates who were brought on after Merrick's captaincy are really pirates, who arguably stored the treasure during a hot pursuit from naval forces, and will soon return to the island to extract their loot.
As Mary, Berg and Stein leave for Haakon's island the next day, Haakon realizes that Merrick and his pirates are returning to the island. Haakon and Jens managed to get help from Berg and Steine. Haakon manages to outsmart the pirates and he, Jens, Berg, and Steine return to their native Norway. Merrick arrives in a hijacked ship to retrieve his loot. Haakon and his friends free them and unite to defeat the pirates, seize the treasure, the ship and the victory. Haakon, Jens, Berg, and Steine are being chased by the pirates, but before Merrick can shoot Haakon, Mary sinks the pirates with a cannon.
Officer Howell. (Howell: Merrick?) Yes, it's me. (Howell: Impossible. Merrick died.) The British Navy did its best, but I'm still alive, my friend. (Merrick's henchman attacks Howell and they surround him) (Howell: You'll not get away with this, Merrick!) Hand over your sailing papers. (Howell: What for?) Because there can only be one of you, and it's gonna be me. Take off your uniform (Merrick's henchman tries to take off Howell's uniform) (Howell: Oh, you look pretty in this uniform, Merrick, but you'll not pass for an officer in her majesty's Navy.)
~ Merrick to Howell before murdering him.
Every ship has its secrets.
~ John Merrick.
I want whoever did this dead. I want my treasure! I want every rock, every hole, every tree on this island searched.
