Howard didn't want to have sex
Why can't we see Leah Thompsons boobies but are treated only to a fake pseudo-human female duck's boobies in the beginning of the movie?
To me, that kind of thinking totally killed this movie. It was an insult really..cause a movie this far-fetched and impossible certainly shouldn't have been above at least treating us to some gratuitous nudity.
Howard's home planet was totally like earth..With that being said, he had total knowledge of sex and what it was. Subscribed to Play-Duck magazine, and had a girlfriend..so he knew of sex. Even had used condoms rolled up in his wallet..out of the damn wrapper.
So why was he afraid to have sex with Beverly? He totally was afraid which didn't make any sense because he knew her well enough.
Were the producers so worried about going too far over the top with implied beastiality? If not, at least have let her take her top off.
