Sudden Terror (aka Eyewitness) (1970)

Set on an unidentified Mediterranean island (it was filmed on Malta), a young boy (Mark Lester) has a history of making up stories and elaborate fantasies. So when he witnesses the assassination of a visiting African dignitary (Tom Eytle) by a policeman (Peter Vaughan), no one believes him ..... except for the assassin who pursues the boy. Based on the novel by John Harris (under the pseudonym of Mark Hebden) and directed by John Hough (LEGEND OF HELL HOUSE). Yet another variation on the "boy who cried wolf" fable. What should have been a crackerjack thriller turns into a messy movie. Every time the tension should be mounting, the film cuts to a tepid romance between Susan George (as Lester's older sister) and a good looking visitor (Tony Bonner) to the island. The film also features two of the worst movie assassins I've ever seen. Clumsy and incompetent, they almost seem like they want to be caught. However, the film's chase finale is well done. With Lionel Jeffries, Jeremy Kemp and Betty Marsden.
