je n'ai pas vu le film ,considérant peut etre à tort que le premier m'avait suffit........
peut etre que cela pourra t'aider :Refilming the ending
In the ending that was originally filmed, Ellen rammed the shark with Michael's boat, mortally wounding it. The shark then caused the boat to break apart with its death contortions, forcing the people on the boat to jump off to avoid going down with it.[1] Test audiences disapproved of this ending. It was remade for the shark to get stabbed with the bow sprit and explode for no apparent reason. Also, this ending had them find Jake wounded but alive. According to Orange Coast, the magazine of Orange County, reshooting the ending prevented Michael Caine from collecting his Academy Award for Hannah and Her Sisters.[8] One version can be seen on cable broadcasts, while the other version is featured on the home releases.[8]
The ending had left many people confused. In his scathing review, Roger Ebert says that he cannot believe "that the director, Joseph Sargent, would film this final climactic scene so incompetently that there is not even an establishing shot, so we have to figure out what happened on the basis of empirical evidence."[9]
