I know you guys were probably wondering what the hell happened with this. The lab guy needed everyone's hard drive so he could transfer all the files and make a DVD with everyone's films. I had to leave the hard drive with him over the entire winter break, so I didn't have access to the files myself until this week.
To make the ghost I filmed the shots with Phil in them and then filmed them without him. I made the shots with him on screen transparent and overlayed them on the shots of just the stationary background.
