`Monster House': Nearly Thrice as Good in 3-D
The 3-D version, shown on 163 screens, earned $16,012, according to E Online.
Quite a diff.
Real D, which makes the 3-D projection gear, put out a triumphant press release:
The 3D per-theatre location average for MONSTER HOUSE was more than $15,000 opening weekend, July 21. More than 11% of the gross for MONSTER HOUSE came out of the 178 screens that were playing the film in the REAL D Digital 3D format – this means that less than 5% of theatres showing MONSTER HOUSE delivered more than 11% of the box-office gross.
(I wonder about the disparity between Real D's numbers and those reported by E Online...but it still looks like a roughly $10,000 difference in per screen average between 2-D and 3-D, whatever the exact tally.)
