I guess it would depend on the definition of a successful movie but here's a couple:
Addams Family Bewitched Charlie's Angels The Flintstones Get Smart Lost in Space Mission:Impossible Police Squad (Naked Gun movies) Serenity (based on Firefly) Untouchables Wild Wild West
Here's some even crummier movies based on tv shows:
The Avengers (Steed & Emma that is, not the upcoming Marvel super-heroes characters) The Beverly Hillbillies The Brady Bunch Movie & A Very Brady Sequel The Fugitive (actually it's not too bad) Scooby Doo and sequel
"Land of the Lost" came out last week, and by all accounts was a successful movie.
"The Incredible Hulk" movies were not based on the tv show--they were based on the comic book which is 15 years older than the tv show.
Incredible Hulk is based on the comic book which preceded the TV show (by about 15 years). Oops. Edited: I missed Ethan's comments which said the exact same thing.
I'll also add another "crummy" movie, based on a TV show: The Honeymooners
Thanks. I didn't know Land of the Lost was a movie first. In fact someone said it was a TV show first. NOW this summer its a totally different way in the movie.
i will go with Quartermass bbc series of the 50's later to be made into i think 3 movies. believe the first movie was hammer's highest grossing movie up to that time.
As someone said, "successful" could have different meanings. But both House of Dark Shadows and Night of Dark Shadows (based on the ABC soap opera Dark Shadows) were successful in the sense that they were profitable for MGM.
