Michael Caine and Sir Laurence Olivier are involved in this routine
movie (probably rent was due and the fellows were late on payment)
which is completely useless. A former British spy who betrayed his own
country is sent back from Russia on a mission. But suddenly (well, not
so suddenly) the story twists to an unexpected (well, not so
unexpected) ending. No actor seems to be interested in what is
happening and the Italian dub (above all Olivier) is rather poor. The
plot makes little sense and . If you look for a spy movie with Michael
Caine, watch "The Ipcress File" or "The fourth protocol",instead. They
would be a very much better choice.
