NEW YORK – One thing hasn’t changed with “Shrek”: Puss in Boots still steals the show.

The fourth and supposedly final “Shrek” film, “Shrek Forever After,” premiered at the Tribeca Film Festival on Wednesday.

It was a glitzy affair for the film, the first in the franchise to be released in 3-D. Given the box-office boost 3-D films have seen the film’s studio, DreamWorks, expects a 3-D “Shrek” to be a hit, capping a franchise that has already earned more than $1 billion at the domestic box office.

“Shrek Forever After,” which will be released May 21, returns the voice cast of Mike Myers (Shrek), Cameron Diaz (Fiona), Eddie Murphy (Donkey) and Antonio Banderas as Puss in Boots, the Zorro-like feline.

The film takes the shape of “It’s a Wonderful Life.” A mid-life crisis comes to Shrek, now a father of three, who laments the loss of his younger, wilder days. Evil magician Rumpelstiltskin (Walt Dohrn) makes a deal, the result being that Shrek was never born.

The bizarro world Shrek encounters is a mishmash of mostly the familiar characters, but with different twists of fate.

In this “Shrek,” Puss in Boots, the debonair swashbuckler, has turned out an obese house cat. He doesn’t even have his namesake’s footwear.

The character, something of a sensation after his debut in “Shrek 2,” won many of the laughs at the premiere of “Shrek Forever After.”

Banderas has said he believed the “Shrek” films have been popular because they’re enjoyed by both kids and parents — “but most especially by the parents.”
