What is martin movie budget?

It seems you're asking about the movie Martin (1977), directed by George A. Romero. Information regarding the budget of Martin is somewhat difficult to pinpoint to an exact figure, but reliable sources often cite it as being made for around 100,000. This was a very low budget for a feature film, even by the standards of independent horror movies at the time.

Because of the limited budget, Romero and his crew relied on resourcefulness and practical effects to achieve the film's unsettling atmosphere and violence. This frugal approach was typical of Romero's early work and became something of a trademark.
