Morgan Freeman, Harry Connick Jr. and Ashley Judd are in negotiations to star in Alcon Entertainment’s 3D family film “Dolphin Tale.”

Alcon co-founders and co-CEOs Andrew Kosove and Broderick Johnson will produce with Alcon marketing topper Richard Ingber, who brought the project to the company. Alcon’s head of development Steven Wegner and Robert Engelman will exec produce.

Principal photography will begin Sept. 27 in Clearwater, Fla. Pic will be released by Warner Bros. through Alcon’s output deal.

Charles Martin Smith (“Air Bud”) will direct from a screenplay by Karen Janszen (“A Walk to Remember”) with revisions by Smith and Jordan Roberts. The script’s based on an original treatment by Noam Dromi.

“Dolphin’s Tale” centers on a young dolphin that loses her tail in a crab trap and an introverted 11-year-old boy who rallies friends and family to save it by persuading a doctor to create a prosthetic attachment to restore the dolphin’s ability to swim. Winter will play herself in the movie.

Freeman will portray the doctor and Connick a marine biologist who rescues the mammal and takes it to the facility he runs. Judd will play the boy’s mother.

It’s the third pairing for Freeman and Judd after “Kiss the Girls” and “High Crimes.” Connick and Judd worked together on “Bug.”

Freeman will be seen next in “Red.” Judd just wrapped filming on “Flypaper.”

Connick and Freeman are repped by CAA. Judd is repped by WME.
