Double Dare, Potter's first work to be shot entirely on film, is a perverse meditation on the relationship between author and subject. Martin is another one of Potter's blocked writers, a motif that appears in Only Make Believe and The Singing Detective. He invites an actress to a hotel for a drink and to discuss his next project. The play he is trying to write concerns a call girl coming to a hotel to visit a client, and Martin hopes the actress, whom he envisions playing the prostitute, will stimulate his writing. Martin relies more and more on a dark secret self to resolve his increasingly schizophrenic artistic crisis. The production is filled with mirrors, traditional symbols of an identity breakdown, and the viewer is never sure what is being portrayed-are we seeing reality or have we entered into Martin's mind? This uncompromising drama refuses to verify any particular viewpoint as it leads towards its horrific finale.
