Tuesday Talkback: High-concept bombs

This week's Tuesday Talkback comes from fellow blogger Kristy at MSP:

Can you think of any high concept movies that exploited their high concept in trailers that bombed in the B.O.?

I know high concept is subjective but my friend and I were going over a bunch of movies with really cool concepts and that had good trailers that exploited those and they all seemed to do really well. I find that trailers now I watch them then I turn to my husband and I say "So what was that movie about?" Because they seemed to be about funny moments or explosions but not really the concept which is the reason I go see movies.

Well folks? Have at it.
