Human figures imported into Bryce are virtually frozen in the pose of their respective obj's and can't be re-animated there. Looks like the Bryce animation was used as background for the figures' animation. Where there are instances of animated figure shadows (not all shots include them) the figure and ground are most likely rendered in Poser or DAZStudio and backgrounded with Bryce. Same for animated figures sitting in chairs or lying down. Both figure and chair or figure and gurney/table also seem to be Poser or DAZStudio renders with Bryce as a background.
