B-movie

A B-movie is usually a low-budget movie crafted by second rate talents and starring lesser-known actors. In the past, these movies were the second feature on a double-bill.  Some actors (such as Bela Lugosi) appeared mostly in B-movies. Today, many of these movies are highly regarded.  Detour starring Tom Neal and Ann Savage, for example, has come to be considered as one of the greatest of film noirs.
