It's not going to happen. Here a comparison:
"There will be blood" box office:
Budget: $25,000,000 (estimated)
Opening Weekend: $302,845 (USA) (30 December 2007)
Gross: 
$40,218,903 (USA) (27 April 2008)

So even if the box office was miserable, there is a chance that the movie will make a turn-around.
