Didn't take long for the media's Concern Trolls to come out:
Mars may need moms, but Tintin needs moviegoers. So it must be worrying to producers/directors Steven Spielberg and Peter Jackson that, even as Disney tries to recover from the disastrous showing of Mars Needs Moms, their own performance-capture 3D production, The Adventures of Tintin: The Secret of the Unicorn, doesn't open until December.
A decade ago, Motion Capture was "The Next Exciting Thing" for filmmakers. They could direct an actor's performance, but because they were capturing the acting digitally rather than with a camera, they could change angles as often as they desired. Move the thesping around. Tinker and tinker and tinker with the digital sets.
Trouble is, MoCap's Uncanny Valley and Living Dead overtones, especially when there's no actual live-action in the mix, isn't a people magnet. This has got to be a concern for studios that have Motion Capture productions in the pipeline.
To paraphrase Sam Goldwyn: "When they don't want to come watch your expensive digital production, you can't stop them."
