An independent horror is a horror movie not produced or financed by a major film company, this also includes films produced and distributed by subsidiaries of major studios. This obviously covers a wide spectrum of movies and the definition has become more associated with low-budget movies distinguishable by their more audacious content and their divergence from the mainstream.
The world of horror movies is renowned for numerous independent productions bringing the director's own style to the screen. More often than not the freedom of independent movie making has allowed the horror director to express their vision as they truly intended and makes the overall horror movie experience a grittier and more in-your-face work of art, embracing all the excesses imaginable with no fear of taboos.
A number of independent studios have stamped their identity on the industry; Lions Gate, Tartan and Troma are all independent and have their own particular style of films but thousands of smaller production companies exist. Troma embraces the independent horror culture and have become eminent for releasing what the general public think is tantamount to an independent production.
