It looks like DreamWorks is hoping to keep up pace with Columbia Pictures in terms of posters for May, 2007 releases. Columbia still has the lead (Spider-Man 3) with three posters while DreamWorks is makes up ground with a second teaser poster for Shrek the Third.
Shrek the Third Poster
Shrek the Third finds the green ogre married to Princess Fiona, but becoming the next King and Queen of Far, Far Away wasn't part of his plan. When his father-in-law, King Harold (John Cleese), falls ill, it is up to Shrek to find a suitable heir or he will be forced to give up his beloved swamp for the throne. Recruiting Donkey and Puss, Shrek sets out to bring back the rightful heir to the throne, Fiona's rebellious cousin Artie. Back in Far, Far Away, Fiona's jilted Prince Charming storms the city with an army of fairy tale villains to seize the throne. But they have a surprise because Fiona, together with her mother, Queen Lillian (Julie Andrews), has drafted her fellow fairy tale heroines to defend their "happily ever afters." As Shrek, Donkey and Puss work on changing Artie from a royal pain into a future king, Fiona and her band of princesses must stop Prince Charming to ensure that there will be a kingdom left to rule.
Moviefone recently got the exclusive on the second teaser poster below featuring the dome of Shrek with a little crown resting on top.
