Oh, I just learned that some of our members from other countries have not heard this expression "B Movie" and wonder what in the heck we are talking about. So here's my shot at a definition. In America we sometimes refer to the quality of a movie like a school child's report card. An "A" is the top grade. "A" movies are like all the star movies such as Lord of the Rings and all the award winning films. They're great. Good actors, great filming, wonderful plot, etc. A "B" movie is one that is generally cheap to make (though not always, just ask Kevin Costner) and always has something wrong with it. Usually bad acting or a stupid plot, but not so bad as to be a movie that nobody wants to see. "B" movies are sometimes copy cats of other better movies. There is something of low grade humor about them, often not intended, but there none the less. We had a series of westerns about a character called "Trinity". It was supposed to be a serious western movie series (I think) and I believe they were filmed in Italy but they were done so badly (and even had lipsynch translation problems with them) that we found it to be a real laugh. We called them "spagetti westerns" and sometimes they were fun enough that folks would buy the tape and play them over and over. Sometimes as the quality of movies increases over time and technology, a movie that was once considered an A movie becomes a B movie. Examples of that would be the original Planet of the Apes series. Golan and Globus were two producers who specialized in low quality low budget films and most of them were worth watching. They actually made stars like Jean Claue van Dam in Cyborg, and Charles Bronson in Death Wish, and Chuck Norris in the Viet Nam "Braddock" movies. The posters that advertise B movies never say that on the poster, but often the producer knows and simply does not spend money on high quality posters. So the posters tend to be low quality as well and sometimes downright awful. Take a look at the posters on those two web sites that Predatron gave, you'll get the idea. There is definitley humor in "B" movies and sometimes its a dry humor or subtle one. There are "C" movies but we usually don't talk about those. They're pretty bad. I'm thinking the black and white Godzilla movies qualify. So a "B" movie is a little bit odd, but still fun to watch and they almost always are action flics. Sometimes just romance. The link above is a good definition of a B movie.
