John Carradine was in a LOT of movies, some good, some OK, some awful. Did the man ever refuse an acting job?

Yeah. He certainly was prolific. Bela Lugosi is another actor who was in loads of films (mostly mediocre or awful) and never seemed to refuse any acting job.

A low-budget B&W horror film with an interesting twist. A mentally disturbed young woman awakes from a nightmare in a cheap hotel room... but was it just a nightmare? The story has a visual film noir style but there's no dialog except from an unseen narrator who occasionally speaks throughout the story while music plays in the background.

An action/crime thriller with Bill Cosby and Robert Culp, teaming up as a couple of struggling private detectives who get hired to find an elusive woman. The trail to the woman leads to several murders and a large sum of money missing from a violent bank heist. Reminiscent of the 'I Spy' TV show that they appeared in together, for several seasons, a few years earlier.

B&W crime thriller about a manipulative crime kingpin on death row, breaking out of prison with help from his gang and some fellow prisoners, just before he is about to be executed in the electric chair.

Another vampire movie. This one is about a vampire living as a nightclub owner in a jungle setting. Rather mediocre movie overall. The most interesting part of the story was that the vampire was a nightclub owner and the nightclub was located in a jungle. No ghosts of any type made any appearances at any time during the story.

Low-budget exploitation flick about prostitution. A young pimp puts his girls to work by dropping them off on the side of roads and having them hitch rides with passing men to seduce them. He befriends the impressionable teenage son of a motel owner, to try to convince him to take over the motel so that he can use it as a base to operate his prostitution business out of. Awful script, awful acting, awful directing, and awful editing, makes for an awful movie. In the right hands, this story could've been wildly entertaining, but alas, it was not to be.

Low-budget crime flick about girls gone bad. Bad directing, bad acting, ridiculous script, unintentionally campy. This is the type of movie that probably inspired John Waters to become a film maker (which is a good thing.)

B&W horror flick about voodoo. A wealthy hotel developer hires a celebrity myth-buster to help him look into the disappearance of 3 of his employees who vanished on a surveying trip to an uninhabited island. One of those films where nothing much of interest happens throughout the story until almost the end, and even then it isn't enough to justify the time spent watching.
