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 -- particularly since "Avatar" -- the film's studio, Dreamworks, expects a 3-D "Shrek" to cap 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.
