Total Film magazine would be the ideal audience for the filmmaker's psychological thriller "The Forgotten Witness" for several reasons: 1) Total Film reviews many thriller films on their website and in their magazines, including smaller independent films. 2) The magazine aims to appeal to the target audience of the film, which is teenagers, young adults, and middle-aged people. 3) Total Film frequently advertises films of the thriller genre both online and in print, which would provide free advertising for "The Forgotten Witness".
