There's probably going to be a lot of mention from critics of Joe Johnston's "Rocketeer." Notice how they skip over Jurassic Park III, Hidalgo, and The Wolfman (Benicio Del Toro).
I think Joe is a very tepid filmmaker, but I still this movie looks somewhat interesting. I had no idea it was a 3D conversion.
I found this article where Johnston explains why he chose to do it in 2D and convert:
Speaking about why he decided to shoot Captain America in 2D and convert versus filming in 3D, Johnston told Earth's Mightiest, "The cameras and their necessary hard and software made up one of the most cumbersome and unwieldy packages I've ever had the misfortune to work with. I couldn't move the camera at a high rate of speed, I couldn't fit it through tight spaces, lens changes took 45 minutes...if the two lenses weren't perfectly calibrated to the exact same focal plane, the shot was unwatchable. It's harder to fast cut an action sequence because your eye needs time to re-establish the depth of each shot. The biggest drawback is that it would have added 30 days to the schedule. For all these reasons and more, I decided to shoot the picture 2D and convert it."
Well, sounds like you need to buck up a little, Mr. Johnston. If Paul Thomas Anderson can do it, so can you.
