Ron Howard directed this hit comedy that stars Tom Hanks as harried businessman Allen Bauer, who as a young boy almost drowned off Cape Cod, but a young mermaid saved his life, and many years later as adults, when the same thing happens again, the mermaid(played by Daryl Hannah) follows Allen home to New York, where she comes ashore nude, making quite an entrance! After Allen takes her home, and names her Madison, they fall in love, which is tested when her secret comes out, and unscrupulous scientists(led by Eugene Levy) want to study her, which will mean her eventual death. John Candy costars as his brother Freddie. Appealing comedy nearly goes off the rails with the kidnapping subplot, but manages to right itself by the end. Good cast helps.
