This is the model sheet thus far. I have decided to expand the goal number to 100 since drawing entire casts has become easier than I thought it would. Right now the count is 67. Not included are Humphrey Bogart (Casablanca), Moosebaby and Susan (Ghost House.) I removed them to either make more space for other movies or because I didn't really like how I drew them, although the latter is far more likely than the former...
Movies represented: RiffTrax, The Room, Birdemic, Plan 9 from Outer Space, Manos: The Hands of Fate, Santa and the Ice Cream Bunny, Twilight, Harry Potter, The Guy From Harlem, The Apple, House on Haunted Hill, McBain, Crater Lake Monster, Ghost House, Future Force, Cool as Ice, Jack the Giant Killer, Viva Kneivel, Norman Checks In, Neutron the Atomic Superman vs. The Death Robots and The Galaxy Invader.

I should probably include more blockbusters and shorts as I work towards the finish line on this whole thing.
