Went back and looked at the past couple years...
In 2009, the top 5 were - Transformers 2, Potter 6, UP, Hangover, Star Trek.
It was not possible for anyone to get 5 out of 5 last summer. Our list of films to vote upon did not include The Hangover. I suppose you could have voted for "other" and listed The Hangover in your post, but no one did that. I think a fair number of people got 4 out of 5 including A-TexDevil, bjornolf, and Udaman. A list of what everyone voted for
can be seen here.
In 2008, the top 5 were - Dark Knight, Iron Man, Indiana Jones 4, Hancock, and Wall*E
Clearly, it would have been possible for someone to pick all 5 of those films. None of them were real darkhorse surprises. Still, none of us picked all 5. Therer were 8 posters out of 66 who voted who got 4 of the 5 right (I was among them).
We shall see what happens this year. I see 3 dead solid locks to make the top 5 this summer.
