Notes on a Season columnist Pete Hammond recently reported Avatar director-writer James Cameron believes that were it not for the Alice in Wonderland, Hubble 3D and How To Train Your Dragon eating up all the 3-D screens in March that Avatar might reach the $3 billion worldwide mark.

I asked Cameron about this myself two nights ago and he confirmed. I don’t know about the $3 billion but he’s almost certainly right that if Avatar could remain in all the 3-D venues it would continue to earn big-time into March and April.
