Honorable Mentions Also Go To...
I didn't offer up these Android movie apps in their own section as they are so specific; whereas the app choices above offer a more general selection of movies, the following relate to specific genres. Still, if you like Horror films or Classic Westerns, you are in for a treat.
130 Legal HorrorFilms, does exactly what you would expect in an app of that name. You also have the added advantage here of knowing that nothing illegal is going on; the films offered are truly free and legitimate. So as these movies are now in the public domain, we are talking true classics of the Horror movie genre, rather than any new releases. You can expect such titles as Night of the Living Dead, Carnival of Souls, Little Shop of Horrors, Dr Jekyl and Mr Hyde, not to mention many other zombie, werewolf and vampire offerings, as well as some Christopher Lee classics.
While 50 Western Movies clearly doesn't offer as many free movies for your Android as the HorrorFilms app, it's still a great choice for wannabe cowboys. Despite having some great Westerns on here (and even some Bonanza TV episodes), it is missing some basics such as the title of the film when you select it, so it's a bit of a Smith & Wesson shot in the dark sometimes. Still, if you like a bit of John Wayne (who makes up the majority of this selection), then you are in for a Wild West of a time.
