It was another slow weekend at the box office, where the new No. 1 movie in America, Bangkok Dangerous, needed a paltry $7.8 million to topple Tropic Thunder, the former champion of the past two weeks. Bangkok Dangerous, an action flick starring Nicolas Cage as a hitman, cost an estimated $40 million to make, so I’m sure studio execs are disappointed with the figures for opening weekend.

Tropic Thunder slipped to second place on earnings of $7.5 million, while The House Bunny delivered a solid $5.9 million.

The Vin Diesel sci-fi action film Babylon A.D. plummeted to No. 6 with earnings of just $4 million.

No other new releases opened this week — perhaps because Hollywood wasn’t eager to compete with the first day of NFL action.

Anyway, here’s the complete Top 10 at the box office for the weekend ending 9/7/08:

  1. Bangkok Dangerous, $7.8 million
  2. Tropic Thunder, $7.5 million
  3. The House Bunny, $5.9 million
  4. The Dark Knight, $5.71 million
  5. Traitor, $4.66 million
  6. Babylon A.D., $4 million
  7. Death Race, $3.59 million
  8. Disaster Movie, $3.3 million
  9. Mama Mia!, $2.71 million
  10. Pineapple Express, $2.4 million
