Eyewitness (AKA Sudden Terror), a British thriller from 1970.
Starring the likes of Mark (oliver) Lester, Lionel Jeffries, Peter Vaughan and Peter Bowles, I was expecting a light hearted and not very thrilling 'thriller'... I think i only watched it to see if Mark Lester could act or not (he really can't)... but since he spent most of the movie looking frightened and running away, his theatrical inabilities were of little concern.
Whilst some of the dialogue is very ropey indeed, there's certain shots and scenes which suggest a very competent director; the elevator scene is beyond brilliant and from there the level of tension just builds and builds. It's hard to take Vaughan and Bowles seriously as the bad guys, but they play a couple of ruthless killers who who don't think twice about shooting a child, her father or a priest. Despite the ropey dialogue and some shoddy acting, this is a very thrilling thriller which i can't recommend highly enough. 8/10
