Our low-budget British psychological thriller film would likely be distributed by a small independent film distribution company rather than a major Hollywood studio. Some potential options are Vertigo Films, DNA Films, and Film 4, which specialize in distributing smaller, independent films from non-professional filmmakers. DNA Films in particular seems well-suited as they have experience distributing similar low-budget, dark genre films like thrillers and our film's psychological thriller genre aligns with the types of films they distribute.
