Impulse is a 1974 American horror thriller film, starring William Shatner as a serial killer of wealthy widows.

[4][5][6] As a boy, Matt Stone (Shatner) became a homicidal maniac after killing his mother's abusive boyfriend in self-defense.

As a playboy conman in adulthood, he has a history of swindling women out of their money, then killing them and moving on to find his next wealthy victim.

He met Shatner at the airport, Bishop was Grefé's friend, and Sakata had a wrestling career there apart from appearing in the James Bond film Goldfinger.

Shatner's then-wife, Marcy Lafferty, has a small role as a motel clerk whom Matt Stone seduces.

The Miami Herald called it a "playful, modest caper" that was "fun... on its admittedly-limited level",[9] while the Tampa Bay Times described it as "interesting but uneven".
