Making a hole in the chest

Ever get that feeling like there a piece of you missing?  Ever want to exemplify that on film but really didn’t feel like taking a trip to the doctor’s office to have some guts removed?  Well, look no further!  In this little exercise we are going to make a hold in your chest so you can pull out whatever crusty organ may be hampering your mojo.  The effect is pretty simple, you have a shirt or other clothing (the above video uses a green cutout and taped it on the shirt) and then key it out on the computer.  But wait, you say, now he’s now three dimensional…well, the video goes on the describe filming and  putting a 3D part at the same angle and composting them together.  Their effect looks okay and could be used more effectively if the shots were setup more carefully so the exact angles and movement matched in the two scenes.
