Which brings me to why you don't want Owen Wilson's agent:
It's not even close. Sure, Double-V's head is lower than OW's, but apparently Vincenzo is a giant. (Or Owen was passed over for the role of Mini-Me only because his nose is crooked.)
If it's still not clear, here's a Photoshopped version of the poster to illustrate how much bigger V
Maybe OW and VV are really good friends and OW doesn't care about his likeness clause. Maybe he'll tell you that he really likes this poster. Riiiiiiiiiiight. This is a town where we get out the ruler on 40 year-old movies to make sure that the billings are the correct percentage of title. Someone fell asleep at the switch. Multiple someones, in all likelihood, since the overall design of this poster is very underwhelming. I understand using the ubiquitous "Comedy White" solution, but couldn't someone come up with a visual concept than this?
