If you like this kind of effect, you should also check out VideoCopilot because inserting 3D objects on top of reference images or video is a recurring use of After Effects (it even ships with a lite version of Cinema4D now). Example with a 3D truck: http://www.videocopilot.net/tutorials/3d_truck_compositing/ http://www.videocopilot.net/tutorials/3d_truck_compositing/ This and Photoshop's context-aware fill (to help fill the holes left from removing the object in the reference image) are very handy to achieve such effects.
