Last week Reuters reported that Jeffrey Katzenberg, co-founder of DreamWorks, announced at the Cannes Film Festival that work had already begun on Shrek 3 and Shrek 4. Now Moviehole has more details on what Katzenberg said.
Before the first one was finished we talked about what the whole story of Shrek is, and each of the chapters answers questions about the first movie and gives us an insight.
Shrek 3 and 4 are going to reveal other unanswered questions and, finally, in the last chapter, we will understand how Shrek came to be in that swamp, when we meet him in the first movie. There is a reason he came to be there, but there is another chapter to the story before that.
