Here are some great shots of Jason from Friday the 13th: Part II that I found in some old Fangoria scans. Some of the shots are well known, in fact they all are being in Fangoria. However, you have got to love these old behind the scenes shots of Steve Dash and Warrington Gillette.
The one I love especially is the one of Jason (Warrington Gillette) crashing through the window at Ginny (Amy Steel). It is a great angle of it and it also proves that Gillette used a pendulum (something he denied) to do this scene. He is clearly on an upward trajectory (hence why his hands are getting farther away from Ginny. Maybe it is not a big deal, but if you were on the old Guts and Gory boards in 2004-6, you'd know why I posted this.
