It's abviously that's not a official poster.
I like the teaser poster for different reasons.
First, it screems out 'Hey, we have Jim Carrey as Dick and he's acting funny!' And it has the same dull spirit that worked for 40-Year Old Virgin. And it does what it's supposed to do, warm up people and make them curious about what the heck Carrey is doin'.
Second. It's clear that it's a bit inspired by the 'Mr. & Mrs. Smith' posters. Funny in a way, also a smart move. So, a second poster for Jane would be great.
Third. 'See Dick Run' is a goof on the idiotic nonsens-taglines on the original movie, which louds 'See Dick and Jane lose everything' and 'See Dick and Jane win evertything back'.
