I'm planning on making 3 combat form costumes, and possibly a carrier form (i want to blow one up haha). I am debating on how to do the infection forms, at least one life size model for direct interaction with actors, and possibly more. I don't really have the computer skills to make realistic infection forms, but you can't have a flood movie without swarms of "puffs" as my roomate calls them. I may make a few infection forms, and make the swarms with some editing tricks. They will essentially be puppets controlled by strings (marionettes?), I've used fishing line to make bullet hit effects, and I think it will work for controlling the infection forms. I'm sure it will take some practice to make it work but I think I can do it effectively. Thanks for all the compliments and input!
