The third and the last sequel to Jaws, released in the year 1987.Ignoring the events of the third film, The Revenge follows Ellen Brody, who finds out that there's a shark attacking people, and shockingly, it seems to be specifically targeting the members of her family.
This time, it's personal:
An Arm and a Leg: The shark rips off Sean's arm before going for the killing strike. Though it's embarrassingly obvious that the actor is just hiding it under his jacket.
Dropped a Bridge on Him: Sean Brody. Though it could have been worse, as the original script had Martin dying to serve as a launchpad for his wife's sunny Caribbean adventure, with even her burgeoning romance with Michael Caine intact. Thankfully, Roy Scheider refused to desecrate his character so much.
Though they still did it anyway—when her surviving son reminds her that Martin died of a heart attack, Ellen claims that "the fear of it killed him!", implying that the repeated encounters with sharks led to Martin's death.
Flashback: While battling the shark, Ellen Brody has flashbacks of events of the first movie that she wasn't even present to.
And events of this movie she wasn't present at (Sean's death), or viewed from another angle (the attack on Thea).
Focus Group Ending: The original theatrical ending had Jake be eaten by the shark and the shark killed by impalement on the boat's prow. However, test audiences were very disturbed by Jake's death, so he (somehow) survives. They also changed the shark's death to massively exploding for no reason whatsoever when it's impaled. The former is ridiculous, but Word of God has it that while the studio demanded changes, they didn't give production appropriate money to re-shoot. (The original intent was the shark to be impaled, die and sink - taking much of the boat with it.)
Impaled with Extreme Prejudice: A ship's bow impales the shark. In the original theatrical version it bleeds to death. In the International version, as they didn't have time or budget to remake the scene in a proper way the shark instead explodes.
Made of Explodium: The shark is hit with the bowsprit of a sailboat and blows up for no reason whatsoever. The original ending had the shark mortally wounded by the impalement and simply destroying the boat with its death throes, and can be seen here.
Nightmare Sequence: Ellen has a nightmare where she is attacked by a shark while swimming.
Not Quite Dead: When Jake is taken by the shark, it seems safe to assume he's a goner, only for him to literally resurface after the climax. This was another change based on the test audiences, who complained about his death in the original script.
Most egregiously, Ellen has sepia-toned flashbacks of events from Jaws, including one of Brody killing the first shark (which she did not even witness). While at the dinner table, Michael's daughter Thea playfully mimics his hand gestures, identical to a scene between Martin and Sean in the original movie, complete with a flashback to said scene.
Brody's elder son grew up to become a marine biologist. Brody's younger son became Amity's Chief of Police. There is a picture of Martin Brody on the wall of Sean's office and he even has a secretary called Polly.
Sean's death in the opening scene of Revenge is reminiscent of Chrissie's in the opening scene of Jaws.
Lee Fierro (Mrs Kintner) and Fritzi Jane Courtney (Mrs. Taft) make cameo appearances. In the original script, Hooper made an appearance too.
Hoagie, Ellen, Michael and Jake paddle back to shore on a piece of wreckage, a la Brody and Hooper.
Revenge even borrows a shot of Bruce the shark's dismembered body sinking after his demise.
Roaring Rampage of Revenge: Revenge makes it perfectly clear that the shark is out for - well - revenge. Extra points for fulfilling the roaring part despite being a shark.
Say My Name: As Jake is seemingly eaten by the shark, Michael screams his name.
