The ensemble cast further reinforces this connection with British genre history. The influence of Tony Tenser is equally apparent. As co-founder of Tigon British Film Productions, Tenser championed low-budget horror that emphasized atmosphere, sensationalism, and provocative subject matter over lavish production values. That film placed a documentary crew inside the Myers house, broadcasting live as entertainment before discovering genuine evil. For admirers of B-picture and “Soho’ style British horror, Harbinger is an engaging reminder that the country’s rich genre traditions remain very much alive.
