‘Don’t Tell Them How They Die’: A Producer Kept Actors in the Dark to Elicit Genuine Terror

Peter Thomas / Frogs (1972) / 1970s

Director George McCowan is remembered for cultivating a supportive set, but one of Frogs’ producers took a decidedly more manipulative tack. Peter Thomas (credited as a producer) deliberately withheld specifics about how characters would be dispatched by the film’s menagerie — snakes, tarantulas, alligators, leeches and more — so that actors would have genuinely startled reactions when the animals attacked. That kind of psychological trickery may have produced livelier screen fright, but it sits uncomfortably on an ethical line: performers were asked to react to staged trauma without full information about their safety or the nature of their exits. In an era when low-budget genre pictures often cut corners, this tactic exemplifies the era’s willingness to prioritize on-screen shock over actors’ informed consent and underscores how producers sometimes manipulated performers for a rawer result. The approach had practical consequences too: actors like Sam Elliott and Joan Van Ark later described the set as a learning ground, but Milland’s very public discomfort and early departure suggest the gambit carried real costs.
