The Man Who Knew Too Much (1956)
Alfred Hitchcock directs as Dr. Ben McKenna's family holiday in Africa takes a nasty turn for the worst when someone they know is murdered on a bus – but not before he divulges details of an assassination plot in London. The assassins fear that their plan may be foiled and kidnap McKenna's son as leverage. Not even Cliff Richard could sing this holiday into a merry affair.
