There were many doubts about how it would work "Green Latern" at the American box office but the last last minute changes in the montage and visual effects and a very strong advertising commitment have made it debut in the USA with 21,6 million dollars, so it will end the weekend close to 60 million and it will not be the fiasco that many commented.
It seems that "Green Latern" yes it is working well in 3D cinemas not like other movies released recently USA ("Kung Fu Panda 2").
Now we will have to wait to see how it works in the rest of the world because in the USA, except for surprises, it will raise just over 130 million dollars.
