A caricature like "GI Joe" presumable can not be used in a movie production without licensing, but what if there is a skit in which one of the retail action figures of him is used. Are licensing requirements the same as just making a model of "GI Joe" to star in your own movie?

Same question for retail purchased Beanie Babies. Can I, without licensing, make at stop action movie using trade marked Beanie Baby caricatures?
