Here are a few web pages for suppliers and other effects companies that can be found on the world wide web.
The Monstermakers - Mask making and effects supply, and distributor of the McLaughlin Foam Latex System, which, in my opinion, is the best and most reliable foam available on the market. Very knowledgeable about all their products, give 'em a call.
Premiere Products - Makers and distributors of a variety of outstanding medical adhesives, removers and hair products. Also, distributor of Green Marble Sealer.
FX Solution - A relatively new kid on the block, but have a good variety of supplies at a reasonable price.
BJB Enterprises - Rigid and flexible urethanes of all type. Casting resins for every purpose. Useful for making both molds and finished pieces.
Factor 2 - Purveyors of medical grade maxillofacial silicone appliance making supplies, as well as supplies for creating artificial eyes. Need this when you decide to start making those silicone gel filled appliances.
Stan Winston Studios - The man who brought you those full sized dinosaurs in Jurassic Park.
Makeup Artist Magazine - A valuable resource for up to the minute news and the latest trends and techniques.
Dick Smith - The web page of one of the pioneers who made this whole thing attainable to the rest of us.
Edge FX - Brought you the Duracell family, amongst other things. Working for Steve Johnson will drive you slowly insane, but you'll dig up personal resources deep within you that you never knew you had, and you'll be a better person for it.
Weta Ltd - The New Zealand company providing the effects for the upcoming Lord of the Rings Trilogy.
Rick Lazzarini's Character Shop - Home of the Budweiser frogs, among other things. Rick is absolutely insane, and a blast to work with. Great informational site.
More to come soon.
