A Poster of The Invention of Lying (2009)

I saw the movie ads on a television channel just now. I thought the campaign poster was similar with another movie last year. I searched it and these are those two poster:

The Invention of Lying (2009)

Yes Man (2008)

I thought those two posters look similar:

1. Both uses blue sky with clouds as the background.
2. Both only view one person in the middle with similar jacket color, hand position, and face expression.
