Seems that when Louis Leterrier was handed the keys to the Greek Gods summer home, Clash of the Titans was born, and if it does well is already planned to be a Trilogy.
After talking about the possibility of releasing an extended version, Leterrier revealed that: “On top of that, I wrote two other movies… It was three movies. Warners came to me and said ‘we’ll greenlight your movie if you promise us [two more.]'” He continues, “You can tell that that story the story doesn’t end at the Clash of the Titans
While the planned Trilogy gimmick seemed to be replaced by “lets make everything 3D!” it seems that the plan is still in motion to create film franchises with intended sequels.
Intended sequels have a little more promise for me as they can work hints and foreshadowing into a bigger story instead of having a stand alone complete story do well at the boxoffice and have the money trucks driving another installment.
I am exceited about Clash of the Titans, and if it lives up I would be eager to see more too.
