Two Fools Catch the Murderer: Following the success of Two Fools in Hell (1958) and Two Fools in Paradise (1958), Sun Ma Si-tsang and Tang Kei-chen team up for the third film in the series. The two fools have finally finished school, but their road to steady employment is fraught with obstacles. Things get worse when their troubled former classmate sets the two heroes up for murder. A spirited take on The Man Who Knew Too Much (1956), the film even includes a cover of Que Sera, Sera as the theme song against hoodlums.
